Equipotential Surface Of A Point Charge

Equipotential Surface of a point charge

Equipotential Surface of a point charge
Definition
An equipotential surface is a surface on which the electric potential is the same at every point.
Properties
All points on an equipotential surface have the same electric potential.
No work is done by the electric field in moving a charge along an equipotential surface.
The electric field is always perpendicular to the equipotential surface.
Examples
For a single point charge, the equipotential surfaces are a series of concentric spheres centered on the charge.
For a uniform electric field, the equipotential surfaces are a series of parallel planes perpendicular to the field.
