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

It is important to note that equipotential lines are always perpendicular to electric field lines. No work is required to move a charge along an equipotential, since Δ V = 0. Thus, the work is.
