Equipotential surface from eight point charges fixed at the corners of a cube August 12, 2010 18 Equipotential Surfaces and Lines ! When an electric field is present, the electric potential has a given value everywhere in space V(x) = potential function ! Points close together that have the same electric potential form an equipotential surface

Unformatted text preview: i.e., V(x) = constant value ! If a charged particle moves on an equipotential surface, no work is done ! Equipotential surfaces exist in three dimensions. ! We will often take advantage of symmetries in the electric potential and represent the equipotential surfaces as equipotential lines in a plane Thursday, September 16, 2010...
