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

resistive devices typically fabricated by laying a strip of resistive ink on a flexible plastic substrate‚ shaped as a thin‚ flexible stripe in lengths between 1” and 5”. At rest (when laid flat)‚ the bend sensor is characterized by an intrinsic resistance. As the sensor is bent‚ the resistive materials inside it are pulled further apart.

Introduction The Carey Foster bridge is an electrical circuit that can be used to measure very small resistances. It works on the same principle as Wheatstone’s bridge‚ which consists of four resistances‚ P‚ Q‚ R and S that are connected to each other as shown in the circuit diagram in Figure 1. In this circuit‚ G is a galvanometer‚ E is a lead accumulator‚ and K1 and K are the galvanometer key and the battery key respectively. If the values of the resistances are adjusted so that no current flows through
