The Electric Field due to a Point Charge
... In any charged capacitor, the electric field near the edges of its plates is not uniform but “fringes”. There is no simple formula for the magnitude of the electric field in this region. The Electric Field Inside a Conductor: Shielding An electric conductor is a material in which electric charge can ...
