Equipotential Surface

In a given charge distribution the locus of points having same potential is called equipotential surface.

(1)  Two equipotential surface can never intersect each other.

(2)  Electric lines of force are always perpendicular to an equipotential surface.

(3)  The component of electric intensity along an equipotential surface is zero.

(4)  The electric field is always perpendicular to an equipotential surface.

(5)  In moving a test charge between any two points on an equipotential surface, the work done is zero.

(6)  Equipotential surfaces indicate regions of strong and weaker electric fields.
