Chapter 17 - Electrical Properties - Misconceptual Questions: 4

Answer

Choice D.

Work Step by Step

The electric field depends upon the change in the electric potential. If there is no change in electric potential, then the electric field is zero. Another way to phrase it is that if the electric field weren’t zero in that region then by using equation 17-4a we could find 2 points of differing electric potential, but that contradicts the assumption that V is constant.
