Equipotential Surface and Its Properties : A surface that has a constant value of potential throughout is known as an equipotential surface . The potential difference between two points on an equipotential surface is zero. Equipotential surfaces are a useful way to represent the potential distribution in an electric field graphically. These surfaces can be represented in two dimensions using lines to help us quantitatively visualise the electric potential in the region. Let us read further to ... Equipotential Surface : Meaning, Definition, and Visual Examples Equipotential surfaces are imaginary surfaces on which the electric potential is the same at every point. Mathematically, all points on an equipotential surface satisfy V = constant, where V is electric potential. Learn about electric equipotential surfaces for IB Physics.
