Equipotential surfaces due to a uniform electric field: A uniform electric field is represented by parallel and equi-spaced field lines. Equipotential surfaces in such a field would be normal to these field lines at every point in the field. Hence, each of these equipotential surfaces A, B, C would be plane and parallel to each other [Fig.]. The surfaces correspond to different potentials V 1, V 2, V 3 respectively; but the potential at every point on any particular surface is the same. In a ... Learn what is an equipotential surface , a surface where the electric potential is constant. Find out the properties, work done and solved examples of equipotential surfaces in electrostatics. Equipotential SurfaceThe surface in an electric field where the value of electric potential is the same at all the points on the surface is called equipotential surface . The potential difference between two points in an equipotential surface is zero. Learn what equipotential surfaces are and how they represent potential distribution in an electric field. See examples of equipotential surfaces for different charge configurations and test your knowledge with questions.
