Question

What is an equipotential surface?

Options

• Any surface over which the electric potential is the same everywhere

• Any surface over which the electric field is the same everywhere

• Any surface on which the electric charge is uniformly distributed

• Any surface where the electric potential increases uniformly with distance

Answer 1

An equipotential surface is defined as the surface at which electric potential is the same at each point. Equivalently, it is the locus of all points in an electric field that have equal electric potential. It is defined by equal potential, not equal field or charge.
