An equipotential Surface is one where all points on it are having same potential. The work done in moving a charge from one pt to another on an equipotential surface is zero. Clearly the equipotential surfaces are normal to the field lines. Hence they cannot intersect as tat would mean two diff directions of elec field intensity which is not possible. So two equipotential surfaces can never intersect.

equipotenial= equal+potential

it means the region which have the same potential.

so how can two potential planes of varying potentials intersect
