Question

Define equipotential surface. Write its characteristics.

✓

Answer

Definition : The surface in an electric field whose potential at every point is equal is called equipotential surface.Characteristics:
(i) The potential difference between any two points of it is zero.
(ii) No work has to be done in moving charge between any two of its points.
(iii) The electric field is always perpendicular to the equipotential surface.
