Note that in this equation, E and F symbolize the magnitudes of the electric field and force, respectively. Neither q nor E is zero; d is also not zero. So must be 0, meaning must be .In other words, motion along an equipotential is perpendicular to E.. One of the rules for static electric fields and conductors is that the electric field must be perpendicular to the surface of any conductor.

Electric potential Today, we focus on electric potential, which is related to potential energy in the same way electric field is related to force. Electric potential, like field, is a way to visualize how a charged object, or a set of charged objects, affects the region around it. A voltage is essentially a difference in electric potential, which
