An equipotential surface is an imaginary surface on which every point has one and the same value of electric potential. ... The work done by the electric field on a particle when it is moved from one point on an equipotential surface to another point on the same equipotential surface is always zero.

What makes something an equipotential surface?

The surface which is the locus of all points which are at the same potential is known as the equipotential surface. ... In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

What is an equipotential surface give an example?

a surface all of whose points have the same potential. For example, the surface of a conductor in electrostatics is an equipotential surface. In a force field the lines of force are normal, or perpendicular, to an equipotential surface.
