At the surface of a charged conductor o
o
The electrostatic field at the surface of a charged conductor is normal to the surface at every point.
For a non-normal Electric field, there is a non-zero component along the normal. Therefore, Electric field should have no tangential component in static. o
Interior of a conductor o
o
There is no electrostatic field in the interior of the conductor. All the excess charge resides at the surface.
Under static conditions, the excess charge resides at the surface of the conductor. On a closed surface, the electrostatic field is zero. So from gauss’ s law, there is no net charge enclosed by the surface. o Throughout the Volume of the conductor
