potential difference is the difference in electric potential (V) between the final and the initial location when work is done upon a charge to change its potential energy. 1 The potential difference can be calculated using the following equation; [2] Where is the work per unit charge done on a charge Q moving it from one point to another against the electric field. If the distance is small the potential difference can be calculated using; [3] If there is no current flowing through a surface, then that surface is said to be an equipotential surface. Current is what causes there to be a potential difference because it is what moves the charges from one point to another. Now potential difference and electric fields can be in three dimensions. But, for the sake of simplicity, the lab has been designed to determine both of these quantities in two dimensions so that we can gain a better understanding of the topic at hand. Equipment: 1. Potential Demonstrator 2. Electrically conducting paper 3. 4 volt dc power supply 4. Digital voltmeter 5. Carbon paper 6. White paper 7. Connection wires: 1 cm probe, banana jacks, safety scissors Procedure:

### 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.
