following: RESISTOR A resistor is a component of a circuit that resists the flow of electrical current. It has two terminals across which electricity must pass‚ and it is designed to drop the voltage of the current as it flows from one terminal to the other. Resistors are primarily used to create and maintain known safe currents within electrical components. Resistors are coated with paint or enamel‚ or covered in molded plastic to protect them. Because

processes. One of the latest areas to benefit from FEA technology is the E-coat paint process. E-coat paint provides for excellent corrosion resistance and is the first of several different protective paint layers applied to an automotive body. During the E-coat paint process‚ an entire automotive body is immersed in a liquid bath. By applying an electrical current‚ a thin paint film forms over all the surfaces in contact with the liquid‚ including those surfaces in recessed portions of the body

Law is the relationship among electric current‚ resistance‚ and voltage. The principle is named after the German scientist George Simon Ohm." Webster’s Online Dictionary. I will be discussing the uses of Ohm’s Law and why it is so important in everyday electrical problems whether it be simple or not. It is everywhere and used by many whether they notice it or not. Ohms law states that current in amperes is equal to voltage divided by resistance. This form of ohms law is most useful for technicians

of an electric circuit. Introduction: This experiment was done in two parts. The first part consisted of understanding how to determine the current‚ voltage and resistance as part of Ohm’s law. The second part consisted of how to use the variables in an electrical current. Knowing how the variables are used in calculations and electrical currents is important in determining the value of the resistor and how it affects the current in the circuit. A device known as the multimeter is used to find the

current would change if the amount of resistance decreased and the voltage stayed the same. Ohm’s law states current is dependent on voltage and resistance. As in any mathematical equation if we change one variable in the equation on one side and leave the other variable constant‚ the other side of the equation will change as well. In this case since current is equal to voltage divided by resistance. If we keep voltage the same and decrease the denominator (resistance) our resulting number will increase

Study about Ohm’s Law: • To verify Ohm’s Law by calculating voltage‚ current and resistance based on different views of Ohm’s law as well as measuring those values to compare the theoretical results with the actual results. • To verify the relationships of R-I‚ V-I and R-V given ohm’s law by increasing one parameter while holding the other parameter constant‚ then measuring and calculating equivalent results of the third parameter. What is Ohm’s Law: Ohm’s Law is made from 3 mathematical equations
