Lab 1: Ohm’s Law Tyler Lotz Aaron Miller January 27, 2012 PHYS202 Section 012 Abstract In this experiment, we investigated the relationship between the electrical current flowing through a circuit element and the voltage applied to test Ohm’s Law. We used various resistors, at specific currents, attached to a power source, an ammeter, and a voltmeter in a circuit series. When comparing experimental values calculated for resistance was compared to the theoretical values, we derived a 6.18% error for 10 Ω resistor and 5.07% error for 50 Ω resistor.

Introduction Ohm’s Law was named after the German physicist Georg Ohm. Ohm’s Law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Ohm’s law says that I=V/R where I symbolizes the current through the conductor measured in amperes. The V symbolizes the potential difference measured across a conductor in volts and R symbolizes the resistance of the conductor in ohms. In this experiment we are trying to see the difference in certain resistors. We are going to determine what voltages are produced when the resistors are set at certain amps. Procedure: Figure 1: Materials used in experiment Before beginning the experiment we had to make sure the power supply was off. To begin the experiment we connected the 10 ohm resistor to the power supply. After setting up the
