Since E = 0 inside the conductor
and has no tangential component on the surface, no work is done in
moving a small test charge within the conductor and on its surface That
is, there is no potential difference between any two points inside or on
the surface of the conductor Hence, the result If the conductor is charged,

electric field normal to the surface exists; this means potential will be
different for the surface and a point just outside the surface
