Reference: AQA
A surface on which the gravitational potential V is the same at every point, so the potential difference between any two points on it is zero.
A surface on which the electric potential is constant, so the potential difference between any two points on it is zero.
A surface joining points of equal gravitational potential, so ΔV = 0 between any two points on it.
