This 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. Introduction One 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 said to obey Ohm’s law or to be “ohmic”.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
