When Equipotential Surface Is Zero?

An equipotential surface is one in which all the points are at the same electric potential. If a charge is to be moved between any two points (say from point A to point B) on an equipotential surface, according to the formula dW=q⋅dV, the work done becomes zero.

What does it mean when equipotential is zero?

This is because, on an equipotential line or surface ΔV = 0, therefore, W =-q ΔV = 0. It means that the work done by the electric field when a charge moves on an equipotential line/surface is zero.

Is electric field zero at equipotential surface?

Electric field is defined as the (negative) gradient of electrostatic potential. There can therefore be no electric field along the line/surface defined by an equipotential.
