    Why are electric field lines always crossing equipotential lines at right angles? Can somebody please explain this to me? Thanks :smile:

    Since the potential cannot vary along an equipotential surface its gradient can only have a component perpendicular to the surface. The electric field is proportional to the gradient of electrical potential. Therefore, the electric field must be normal to an equipotential surface.
