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
