Jump Ship To Freedom Essays - , Term Papers

Jump Ship To Freedom This book was about slavery and Arabus who wanted to be free and not have to answer to his slave master Ivers who treated him like dirt. It is hard to compare Arabus and me because there is not much in common between us. One thing we have in common is that we both believe that African Americans should not be discriminated apart from white people. Something that we don't have in common is that his father is dead and mine is not. We both have determination. Arabus was trying to become free by stealing his Fathers soldiers notes and then sailing with Ivers all the way to New York and then jumping off and swimming away from Ivers so he could find his fathers old friend and trading in his dads notes for money and then he could by his freedom and then buy his mothers freedom. I have never had to fight for my freedom but I think I would have the determination to fight for my freedom. We can both swim well. He proves he is a good swimmer when he jumps off the ship and swims away to get to New York. I have never proved I'm a good swimmer by swimming away. People know I can swim well because they have seen me swim at the pool. I don't think that I could swim away for as long as he did. The last thing that I will compare is the fact that he lost his dad when he was really young and I still have mine. His dad was a soldier that was fight and his ship sunk and was African American . My dad is not a soldier and he is not There are differences but I think we could be friends if we were the same age because we have the same morals. What we don't have in common are little things that don't matter as much.

10 Best Proposal Examples [With Critical Critiques]

10 Best Proposal Examples [With Critical Critiques] Earning more business starts most often with an effective proposal. Preparing a winning proposal means writing for the client and providing a clear, valuable solution to their problem. For every Request for Proposal (RFP), there are good and bad proposals. To understand how to improve your submissions, we have reviewed ten great examples. These examples are prepared by proposal software companies. All are free to view without registration. In this article, we will review these examples highlighting both the best practices used and common mistakes to avoid. If you are looking to create a winning business proposal for your company we suggest taking our proposal writing training course. 1. Digital Marketing Proposal This proposal is effective because it provides a clear, specific solution to the client’s problems. It opens with a value-oriented executive summary. The scope of services provides brief but informative summaries of the offered services. The very first paragraph states the specific benefits to the client. â€Å"... we are confident we can significantly increase your site traffic, customer engagement, and on-site conversions.† The timeline and the budget, persuasively phrased as ‘Your Investment’ are straightforward and easy for the client to understand and decide upon. The case study placement is a bit distracting, as it could be included near the end with the About Us section. 2. Financial Services Proposal The flow and content of this proposal are strong, with one significant exception: the About Us section. While the About Us and Team sections do add value, the client is most interested in the solution. If the solution is appropriate, then the people behind it are the next consideration. The first-page executive summary should be a convincing and specific overview for the reader. This section along with proposed service details, timelines and budget are read in depth. The About Us sections are simply skimmed. Whether using a software or your company’s template, present the client with the most important information first. Make it easy for the client to understand and see the value in your company's proposal. 3. Web Design Proposal This document clearly outlines the process for implementing the proposed services. The financials are broken down so the client can understand unit, hourly, and subscription costs. However, the About Us and Team sections come just after the introduction. Ensure the solution sections come first. 4. Engineering Services Proposal Here, the Project Background sections clearly outline the work process for the client. Each task is clarified and seems to respond to specifications of an RFP. Using client specifications to prepare a proposal makes it easier for the reader to understand how your solution directly solves their problem. This section is strong and should come just after the executive summary. However, the introductory summary should include more persuasive and specific language. As noted previously the Introduction and Team sections should fall towards the end of the proposal. Always lead with the benefit to the client. It’s not about your business. The focus should be how your business can help the client. 5. CRM Implementation Proposal The introduction or executive summary uses convincing language and bullet points to highlight the value. It could be improved by shifting the language from general CRM best practices to how the company can specifically offer them based on this proposal. Again, the About Us section should come after the proposal benefit-to-client details. 6. Freelance Writing Proposal A sleek web-based proposal that includes specific offerings and clarification of the value. The Introductory letter and Executive Summary have strong, persuasive elements that refer to specific client needs. These two elements could be combined to strengthen the first section. Again, the About Me should be presented after the solution.7. Insurance Services Proposal A brief proposal that covers a range of offerings. Nice overall use of white-space to allow the reader to skim and find the important information. The lengthy paragraphs could be shortened to increase readability and add to the white-space. Remember what we said about About Us? 8. Interior Design Proposal A visually compelling document suited for the industry. Bumping up the Project Showcase section would improve proposal flow.9. Graphic Design Proposal A simple but effective proposal. The introduction focuses on client needs (and would be more specific in a real-world document). Credentials, Testimonials, Selected Works should come after the Project Summary. 10. Project Management Proposal A thorough, understandable proposal that breaks down the process and pricing. The content highlights the company’s knowledge of client needs and their value proposition. However, the executive summary leaves much to be desired. Every sentence should be persuasive and specific, whereas this text is uninspiring and unclear. Conclusion Your proposal is your direct chance to win new business. Keep the client in mind in each step of proposal preparation. This strategy may mean revamping existing templates or starting fresh. Take the best parts of these examples, avoid the mistakes, and put your best foot forward to help the client.

Metals and corronslon Lab Report Example | Topics and Well Written Essays - 500 words - 4

Metals and corronslon - Lab Report Example Metals react with acids to give the metal salt and water. The purpose of this experiment is the determination of the different properties of metals. The properties determined include conductivity, hardiness, and Brittleness. Also, the ability of copper, iron and brass to resist corrosion was investigated in this experiment. All the three metals were placed in three different open beakers containing tap water and left there for 3 days. After the tree days, it the changes in the physical appearance of the metal was observed and recorded When one end of the three metals were heated and time taken for the heat to be transfred from the end being heated to the other opposite end taken, it was found that it was faster in copper than in iron and brass. From the experiment, it can be determined that iron and brass are prone to corrosion as compared to copper. Also, comparison of the brittleness of the three indicates that iron is more brittle as compared to copper and brass. The alloy of copper and iron, brass is harder than the pure metals. From the experiment, it can be concluded that copper metal is a good conductor of heat, iron is more brittle and brass is harder. Also, it can be conclude that, substances containing iron are more prone to corrosion as compared to substance lacking iron. This due to the presence of iron II Oxide that is converted to iron III Oxide which is the rust that causes

Human Resources Quiz Assignment Example | Topics and Well Written Essays - 1000 words

Human Resources Quiz - Assignment Example The value to the organization is encouraged and motivated employees if positive feedback is offered that can lead to better competitive advantage and human capital development. It builds productivity in worker groups and promotes teamwork if performance is linked with reward or discipline systems. Performance management helps leaders and managers identify better methods for improving motivation and loyalty and also sets important standards for how to reach important long-term goals and satisfy the corporate mission. The value for the individual is better cooperative behaviors that build teamwork, better relationships with the human resources manager and line managers, and gives them opportunities to develop skills. Results-based rewards can build self-confidence and esteem. If the job criteria is clearly listed and they understand, through the performance management system, how to reach goals, the employee will feel valued and more empowered. Question 2 The term business is behavior means that in order for a company to be successful, it relies on the talents, ambitions and productivity of workers. Employees need to have a positive attitude in areas of customer service and in terms of their relationships with co-workers and management staff. ... Unbreakable behavior laws are those behaviors that do not change over time and have to do with human behavior internally. There are fundamental inherent beliefs that do not change as related to culture and background that are created by family or lifestyle that will not change without significant effort on behalf of the business leaders, therefore considered unbreakable. Behavior is key to quality because of the many outputs that a business relies on to be successful in achieving its goals. Quality means satisfying customers, making sure their jobs are performed properly the first time, and even in relation to training packages. Employees who are not motivated will exhibit poor behaviors and the quality of their work will be lessened. Therefore, human resource managers must try to satisfy employees with appraisal-based rewards or simply improving their job environment so that they remain loyal. Without these elements, there is no quality outputs. Question 3 Pinpointing is a precision effort to identify specific goals or targets and then setting about the task of developing programs to support what has been discovered through this research. It is an exacting science of understanding in exacting detail the behaviors that one wants to be able to influence. Pinpointing is ensuring that the human resources manager does not get off track and develops only the type of training or development needed to reach a very specific goal. For example, if a company needed to reduce costs in the customer service call center, they would only target this division and focus on job roles at the individual level to identify areas where savings can be found. It prevents duplicating efforts and helps to remain specific before developing an appropriate program of action. Pinpointing applies

Is Adorno being elitist when he criticises the culture industry Essay

Is Adorno being elitist when he criticises the culture industry - Essay Example ts came from educated-in-elite-school-system Germans such as Schopenhauer, Martin Luther, Immanuel Kant, Karl Marx, Friedrich Nietzsche, Bach, Beethoven and Goethe. There was a point in time where the German elite formed the main part of the intelligentsia. â€Å"The Germans are literary people. The country is after all das Land der Dichter und Denker, the land of poets and thinkers.† (Wasser, 2006) To understand whether Theodore Adorno in his criticism of art, music and culture was guided by the moralist, egalitarian, capitalist or totalitarian stance, this paper will focus on Adorno’s biography and his contributions to the development of the culture industry as well as his critical views on music and popular culture. For the purpose of clarity and space, Adorno’s early works (1941-1941) will be used as reference to build the entire paper. In 1903 in Frankfurt, Germany, Theodore Adorno opened his eyes to an affluent and educated family. Both â€Å"his mother and sister were accomplished musicians and it was from them that he received his initial training and encouragement in his life-long love for music† (Jay, 1973). His Jewish roots ultimately became the deciding factor in his philosophical writings and thoughts, especially after Hitler’s totalitarian regime and the Nazi Holocaust swept over Germany with millions of Jews persecuted under it. During this time, Adorno was forced into exile and spent the next 16 years of his life in England and the US before returning to Germany to complete his doctorate in Philosophy from Frankfurt University. Adorno’s position on culture and the music industry has managed to establish key influences in the domain of media studies. His ideas about these industries were critical and in some cases, pessimistic. Adorno analyses the dynamics of the culture industry in the context of ‘standardization’ underlining it as a fundamental characteristic of pop music. He quotes himself: â€Å"A clear judgment concerning the

Linear And Non Linear Voltage Divider Engineering Essay

Linear And Non Linear Voltage Divider Engineering Essay The report describes an investigation of how linear and non-linear voltage divider type of circuit relies on the application of Ohms law (1). The linear circuit was consisted of series resistors. Separating the total resistance of the circuit into two parts, the circuit functions as a voltage divider across which output voltages, and are taken. The report hence is also study the operation of a voltage divider and finds that the total voltage drop around a single close path divides among the series resistors in amounts directly proportional to the resistance values (2) so the formula where and are the output voltages across the resistance and respectively was derive. The investigation was conduct under range of DC and AC input voltages so the ratio between the output voltages was compared to the required ratio of 2:1. This was successfully matched within the tolerance of  ±5% thus; the proportionality of the output voltages to the input voltages proves the linearity of the circuit and it applicability to Ohms law. The non-linear circuit was consisted of 1kà ¢Ã¢â‚¬Å¾Ã‚ ¦ resistor and a filament bulb. The investigation was conduct under range of DC and AC input voltages and shows that the recorded measurement of the output voltage across the bulb, , was not showing linear trend with respect to the input voltage, . Inspection of the IV chrematistic of the filament bulb shows that the bulb is a non-ohmic conductor. Looking at the linear band the resistance of 61.2 à ¢Ã¢â‚¬Å¾Ã‚ ¦ was found Introduction Work objective Choosing the right apparatus and components is essential when designing electronic circuits. This needs to be done carefully so the measurements will be as accurate as possible. This report aims to find a procedure of choosing the right resistors and the method of using them. This concept together with how to recognise resistors values, measuring potential difference across a component and the physics of the filament bulb will be examined in the background to the experiment work. Understanding the specification set out in the task is key factor in completing the practical work. The report will examine the theory applied to the voltage divider and by using the definition of current, voltage, electrical resistance and power, the report will obtain the voltage divider formula and the assumption that these formula are based on. The report will then present the prediction based on the theory. The report will show the method of how the wide range of reading is to be taken and explain which variables are going to change and which variables will be kept the same. Also, the particular method to test the prediction and completing the exercise script will be presented as well as the reason for why this method was chosen. Finally, the report will analyze one of the simple basic circuits: the voltage divider. The report will evaluate the evidence and procedures and a comment on the accuracy and reliability of the result. The last section will suggest ways the measurement could be made more accurate and reliable and how this experiment might be extended. Background to the experimental work RESISTOR POWER RATINGS The amount of power in a resistor is important because the power rating of the resistor must be high enough to handle the expected power in the circuit. The resistors used in this experiment are type CRF16. These have small case size and full power rating of 0.25 W. To specify the required minimum resistance the following procedure is adopted: Determine the total resistance: The total series resistance, , is the sum of all resistors in the series circuit. Next, the current, , need to be calculated. When resistors are connected in series and a voltage is applied across the series connection, there is only one path for current; therefore each resistor in series has the same amount of current through it. Using Ohms law which states that the current is directly proportional to voltage and inversely proportional to resistance (1) the equation: where, is the source voltage is derive. Then the power, , in each resistor is: Substituting (1.1-2) into (1.1-3), the following equation is obtained: rearranging to rescue : THE RESISTORS COLOR CODES The resistors used in this experiment are common fix resistor constructed using carbon film. The resistive carbon evenly distributed along the high-grade ceramic rod. In order to differentiate between the resistors value and confirming the values and tolerance when they are connected to the circuit, a color coding system is used. The resistors used in this experiment are coded with four bands. The first and the second band closer to the end represent the first and second digit respectively. The third band represents the multiplier, i.e. the number of zeros following the second digit. In this experiment the last band represent tolerance value of  ±5% and it is a gold color. The table in appendix 3 shows the resistance value of a resistor with 4-band color code. MEASURING VOLTAGE A DMM has a floating common, so it can be connected to any point in the circuit and read the correct voltage between the two leads. Measuring voltage with oscilloscope may create a grounding problem since the generator and the oscilloscope have a common ground. The problem occurs when trying to measure the voltage across the component that is not connected to ground. Trying to do so, will effectively short out of the circuit all the components that connected from the terminal at which the measurement is taken to the ground terminal and the voltage measured is meaningless. This is become very important when current sensitive components like the filament bulb are connected in the circuit. The resistor is therefore the current limiting impedance. Shorting out the resistor could raise the current to levels that could cause permanent damage to the bulb. The solution to the problem is usually to recognise the grounding points of the circuit and connecting the oscilloscope to these points only. To find out the voltage across the component which is not connected to ground, the method used is to subtract the measured volt age from the input voltage THE FILAMENT LAMP (7) The filament is made of tungsten wire and it is essentially a device for converting electrical input energy into an output of radiant energy in the form of light and heat. According the temperature at which the filament glows will determine the appearance of the light emitted. The tungsten wire is very fine in diameter; the wire is coil as shown in Fig. 1.1.4-1. The closer the spacing of the coils the hotter the filament can operate. The filament lamp to be used in this experiment is yellow filament lamp size 4mm and it is rated at 12V, 30mA with output energy of 0.7 Lumens. The ideal operation condition for AC is stabilized 50Hz. This bulb is sensitive to operation with DC as the one direction current flow causes an effect named DC notching where the filament wire is becoming weak. The report will define the metal (tungsten) filament lamp device by the current voltage (I/V) characteristics and will explain the difference in behavior of the tungsten filament light bulb. Figure .1.4-1 Single Coil filament (7) UNCERTAINTY IN CALCULATED VALUES (8) The arithmetic mean ratio, , will be calculated by the following equation: (1.1.5-1) where can have any integer value, is the number of observations and represent any of the observation. Having obtained a mean value, , the precision of the experiment will be quantified by using the equation for standard deviation, , for the special case where all data points have equal weight (1.1.5-2 ) The standard deviation, defined by Eq. (1.1.5-2) provides the random uncertainty estimate for any one of the measurements used to compute . The standard deviation of the mean value of a set of measurements , when all measurement have equal statistical weight is given by The results in this report will be stated in term of the percent or fractional uncertainty, . Multiply by 100. The relationship between and is as follows Theory Governing equations This section will consider a single-loop circuit, as shown in figure 2.1-1 in order to develop the equations relative to the experiment. The direction of the resistor voltages and current are marked according the convention set by Ohms law: Electron flow current is defined to be into the negative side of each resistor and out of the negative side of each resistor and out of the more positive (less negative) side. With regards to the source electrons flow current is defined to be out of the negative side of a source and into the positive side. Figure .1-1 Single-loop circuit with voltage source vs. Using Kirchhoffs current low at each node. The following four equations can be obtained: (2.1-1) a: (2.1-2) b: (2.1-3) c: (2.1-4) d: Each of these equations can be derived from the other three equations. Since the current is the same at all point in a series circuit the following equation is noted: so that the current can be said to be the loop current and flows continuously around the loop from a to b to c to d and back to a. The connection of resistor is Fig 2.1-1 is said to be a series connection since all the elements carry the same current. In order to determine, we use the principle of superposition where voltage sources in series add algebraically and Kirchhoffs voltage low around the loop: The sum of all voltage drops around a single closed path in a circuit is equal to the total source voltage, in that loop. (2.1-5) where are the voltage across the resistors . Also from Kirchhoffs voltage law: The algebraic sum of all the voltages (both source and drops) around a single closed path is zero. The voltage drops in a circuit are always opposite in polarity to the total source voltage. Eq. (2.1-5) can be written as: (2.1-6) Using Ohms law for each resistor, Eq. (2.1-6) can be written as: Solving for , we have Thus, the voltage across the nth resistor is and can be obtained as A voltage drop results from a decrease in energy level across the resistor. A voltage divider is a series arrangement of resistor connected to a voltage source. Thus, the voltage appearing across one of a series resistors connected in series with a voltage source will be the ratio of its resistance to the total resistance. This circuit shown in Fig 2.1-2 demonstrates the principle of voltage division, and the circuit is called a voltage divider or potential divider In general, the voltage divider principle is represented by the equation where , is the voltage across the nth resistor of N resistors connected in series. A voltage divider is so named because the voltage drop across any resistor in the series circuit is divided down from the total voltage by an amount proportional to that resistance value in relation to the total resistance. Comparing the circuit shown in figure 2.1-1 and the circuit shown in figure 2.1-2, the current are identical when and the resistance is said to be an equaivient resistance of the series connection of resistors and . To determine the resistance and required so that the ratio between the voltages cross and will be 2:1 we consider the voltage across the first resistance And across the second resistance The lab script desire, so division of the first equation in the second results The constant of proportionality is called the gain of the voltage divider. The value of the gain is determined by the resistance RA and RB (4) Choosing the value of the resistors. It wasnt possible to chose values The total resistance between any two points in a series circuit is equal to the sum of all the resistors connected in series between those two points. In our simple circuit if the voltage source connected to a resistance Rx and Ry as shoen in figureà ¢Ã¢â€š ¬Ã‚ ¦, for this circuit If all the resistors in a series circuit are of equal value, the total resistance is the number of resistor multiplied by the resistance value of one resistor. The total power in a resistive circuit is the sum of all the individual powers of the resistor making up the series circuit. Ground (Common) is zero volts with respect to all points referenced to it in the circuit. Negative ground is the term used when the negative side of the source is grounded. Positive ground is the term used when the positive side of the source is grounded. The voltage across an open component always equals to the source voltage. The voltage across a shorted component is always 0 V. The circuit constructed was consisting of series string of resistors connected to a voltage source. Although there can be any number there are two voltage drop across the resistors: One across R1 and one across R2. These voltages drops are V1 and V2 respectively, as indicated iun the schematic. Since each resistor has the same current, the voltage drops are proportional to the resistance value. For example if R2 us twice of R1. Then the valye of V2 is twice that of V1. The total voltage drop around a single closed path divides among the series resistors in amounts directly proportional to the resistance value. The voltage divider is an important application of series circuits. This report will derive and apply the voltage-divider formula in order to obtain ratio of 2:1 between output voltages. A series circuit can have only one path for current. The total resistance of a series circuit is found by the following equation: Kirchhoffs voltage law Total power If three equal resistors are used in a voltage divider, the voltage across each one will be one-third of the source voltage. A potentiometer can be used as an adjustable voltage divider. The essential circuit of a voltage divider, also called potential divider is: The voltage divider equation can be written as The power dissipated by the resistor in a series circuit is the same as the power supplied by the source. The theory applied to the circuit consists of a few calculation to develop a formula for determining how the voltage divided among series resistors. The resistance between two terminals can be considered as one part and the resistance between other two terminals can be considered as another part. The knowledge of how the filament lamp behaves under varying conditions of current and voltage is essential in building electronic circuits consists of the filament lamp therefore characteristic would be shown as a graph of the current (y-axis) versus voltage (x-axis) for the filament lamp. It will show how the electric current flowing through the component varies as the voltage across the filament lamp is gradually increases by the experimenter. The electric current in this experiment is the dependent variable i.e. it is dependent upon the voltage setting chosen by the experimenter. Assumptions statement The resistors used in this experiment are given with a certain tolerance of 5% The exact resistor values dont matter, so long as their ratio is correct The formula and the approximate rules given above assume that negligible current flows from the output. This is true if Vo is connected to a device with a high resistance such as voltmeter or an IC input. Experimental procedure and results Experimental procedure APPARTUS AND COMPONENETS To carry the experiment the use of the following apparatus and components is required: Breadboard Black wire to connect between the circuit and the negative supply terminal Red wire to connect between the circuit and the positive supply terminal EL302Tv DC Power Supply to supply DC voltage MTX3240 5MHz Signal generator TDS2002B digital oscilloscope to measure the output AC voltage Fluke 115 digital multimeter to measure output DC voltage Resistor Carbon Film 5% 0.25W brown-black-red-gold Resistor Carbon Film 5% 0.25W brown-black-red-gold Resistor Carbon Film 5% 0.25W brown-black-red-gold Filament lamp T1.25 12V 30mA, bi-pin 2 Croc Clips T-Piece Electronics Test Probe REPERTORY OF METHODS The set up of the apparatus needs to be done correctly and skilfully. The quantities measured are Checking for errors in the measuring instruments and the need to take action should errors are found This experiment begins with the three 1 kà ¢Ã¢â‚¬Å¾Ã‚ ¦ carbon film resistors with tolerance of 5% and power rating of 0.25W. Confirming the right resistors are used by comparing it with 1 kà ¢Ã¢â‚¬Å¾Ã‚ ¦ colour coding: Brown-Black-Red-Gold and measuring and recording their values as R1, R2 and R3 Connecting the two legs of the resistors in series on the bread board. Connect the bread board to the power supply and the multimeter as shown in figure . the negative terminal of the power supply and the red probe to the positive terminal of the power supply to record the source voltage Vin, move the red probe to the terminal point A to record the voltage drop across R1. To record the voltage across the upper resistor change the multimeter connection to the circuit as shown in figure. noting the voltage drop across the other two resistors as V2 The main function of the 1 kà ¢Ã¢â‚¬Å¾Ã‚ ¦ resistor in this circuit is to control the current and the voltage across the lamp. If too much current flow through the filament lamp it is destroyed so the resistor is used to limit the current. Connect the circuit on the bread board as shown if figure below Measure the source voltage, VS and the voltage across the filament, Vf for different Source voltage as shown in table 2.

This is because Results [The results that appear in this section will be those on which the discussions will be based and from which the graphical plots will be represented. Results will normally have the units of the SI, although some may have traditional units, e.g. motor speed/rpm.] Table 2 Amplifier gain as a function of frequency from the measurements of input signal amplitude and output signal amplitude the voltage gain has been calculated as shown in Table 2 Axes shall not have arrow heads at their ends, and division marks on an axis shall not be closer than 20 mm. Data points should preferably be shown by small circles, squares or triangles with a dot in the centre; crosses, either vertical or inclined, may be used when all other options have been exhausted. Do not use colour to differentiate between curves on the same figure; use different legends (e.g. circle and square) and perhaps different line types (e.g. continuous and broken). Give a legend key to describe the curves. Keep a figure free from extraneous text and lines, such as a right angle and a calculation to determine a slope. It would also help to show a thin lined grid. Discussion Interpretation of and/or commentary on the results The discussion is the interpretation of and/or commentary on the results and the reasoning on which the conclusions are founded. For example, in a figure showing the variation of voltage gain of an amplifier with frequency might exhibit a slight increase in gain at high frequency before the main fall off in gain. Your text in the discussion should give reasons for this behaviour. A variable resistor which can be varied by moving a knob or slider could also be used for this experiment. Connecting the pots three leg so it could act as a potential divider. Adjusting the potentiometer mechanism until the voltmeter register exactly 1/3 of total voltage between the wiper and the positive terminal and checking that this ratio maintain for double the voltage. Precision estimation It is in the Discussion section that an estimate of the precision of your results should be given. Conclusions The conclusions represents a clear and orderly presentation of the deductions made after full consideration of the results of the work. .. the details of an involved argument or result should not be included. Making sure that the power ratings of the resistors are adequate for the application Not all componenets obey Ohms law for the variation of current with voltage. Ohms law describes the behaviour of metals but even for these materials the law is only obeyed under very specific conditions of constant temperature and pressure. Thus Ohms law describes obly the behaviour of one type of material (metals) under very specific conditions. The voltage divider is a very important basic circuit. The voltage divider is a very simple circuit that can be highly accurate if not loaded down. Understanding the principle of voltage divider helps in designing sensor systems and guide how to provide reference voltages to an electronic circuit in an analog-to-digital converter. use resistors in an appropriate configuration. low resistance values will draw a significant amount of current from the original source. This is probably acceptable if the original source is an electronic power supply, but not if its an actual battery. Thus, this use of a voltage divider is reasonable and appropriate in some circumstances, but not in all cases The proportionality of voltage drops (ratio of one to another) is strictly a function of resistance values. the voltage drop across each resistor is also a fixed proportion of the supply voltage. The voltage divider is a very important basic circuit, and exploring the calculation above with various values can give you insight into a large number of practical circuit applications. The ratio of individual resistance to total resistance is the same as the ratio of individual voltage drop to total supply voltage in a voltage divider circuit. This is known as the voltage divider formula, and it is a short-cut method for determining voltage drop in a series circuit without going through the current calculation(s) of Ohms Law. Voltage dividers find wide application in electric meter circuits, where specific combinations of series resistors are used to divide a voltage into precise proportions as part of a voltage measurement device. nn linear resistance thus Ohms law is only applicable at the linear band of the bulb resistance which is found to be 61.2à ¢Ã¢â‚¬Å¾Ã‚ ¦. conclusions about the work you did including any suggestions or modifications to the experiment

Internet Censorship :: essays research papers

Internet Censorship For centuries governments have tried to regular materials deemed inappropriate or offensive. The history of western censorship was said to have begun when Socrates was accused "firstly, of denying the gods recognized by the State and introducing new divinities, and secondly of corrupting the young." He was sentenced to death for these crimes. Many modern governments are attempting to control access to the Internet. They are passing regulations that restrict the freedom people once took for granted. The Internet is a world wide network that should not be regulated or censored by any on country. It is a complex and limitless network which allows boundless possibilities and would be effected negatively by the regulations and censorship that some countries are intent on establishing. Laws that are meant for other types of communication will not necessarily apply in this medium. There are no physical locations where communications take place, making it difficult to determine where violations of the law should be prosecuted. There is anonymity on the Internet and so ages and identities are not known this makes it hard to determine if illegal activities are taking place in regards to people under the legal age. As well, it is difficult to completely delete speech once it has been posted, Meaning that distributing materials that are obscene are banned becomes easy The American Library Association (ALA) has a definition that states censorship is â€Å"the change in the access status of material, made by a governing authority or its representatives. Such changes include: exclusion, restriction, remove, or age/grade level changes.† This definition, however, has a flaw in that it only recognizes one form of censorship-governmental censorship. Cyberspace, a common name for the Net, has been defined by one author as being "made up of millions of people who communicate with one another through computers. It is also "information stored on millions of computers worldwide, accessible to others through telephone lines and other communication channels "that" make up what is known as cyberspace." The same author went on to say " term itself is elusive, since it is not so much a physical entity as a description of an intangible."
