Unformatted text preview: PH-202-L-P1Experiment 3: Ohm’s LawAbstractThis lab involved exploring the relationships between current, voltage, and resistance known as OHM’s law. Part A of the experiment, involved varying the voltage to observe the effects it had on the other two parameters. For part B we varied the resistance to see its effects on the other two parameters. The value of the resistances were found to be 4,9114 and 1,177.8 which showed a percent error of 4.55% and 11.78% respectively.IntroductionOne of the most applied relationships in current electricity is that known as Ohm’s law. Ohms law relates voltage (V) and current (I) associated with a resistance (R). However, when a voltage or potential difference is applied across a material, the current in the material is found to be proportional to the voltage. The resistance is defined as the ratio of the applied voltage and the resulting current. For many materials, the resistance is constant over a range of voltages. A resistor that has a constant resistance is...
