Electric Potentials & Fields

Summer Session II 2010

• In what regions is the maximum potential difference the largest? Where is it

the smallest?

• What is the relationship between the direction of the maximum potential

difference and the surfaces of our conductors?

• What relationship do these arrows have with the electric field? Defend you

answer with evidence from this lab.

• Use your measurements from C1 and C2 to calculate the magnitude of the

electric field at the different points you measured.

Activity D: Find a unique own geometry.

D1. Get a sheet of Teledeltos paper that has a unique geometry from the TA. Make sure

that the geometry has two objects that are not touching. Copy your drawing onto two

white photocopies of blank Teledeltos paper.

D2. On one of your copies, draw a prediction of where the equipotential surfaces will be.

On the same sheet and in a different color, draw a prediction of where the electric

field lines will be.

D3. Using the methods described in Activities B & C, find two equipotential surfaces and

the electric field at several points. Make sure you measure enough points to draw at

least two electric field lines.

D4. Do your measurements agree with your predictions? If not, how are they different?

Can you explain why they are different?

Conclusion:

1. Please do a write-up for the section of the lab that your TAs specified.
