3 cards from this section. Quick, good the night before a test.
Define an equipotential surface.
Think about potential energy remaining unchanged.
What shape do equipotential surfaces take around a point charge?
Consider how potential changes with distance.
What is an equipotential surface?
Think about where work is done on or against electric fields.
True or False: No work is needed to move a charge along an equipotential surface.
Remember the definition of work done in electrostatics.
A point charge +Q is placed at the origin. Calculate the potential at a distance r from the charge. Further, describe the equipotential surfaces around this charge.
Use the formula for electric potential due to a point charge.
Considering a parallel plate capacitor with a uniform electric field, define how the distance between equipotential surfaces relates to field strength.
Think about the relationship between E, V, and d.
