Electric Fields Inside of Charged Conductors Charged conductors that have reached electrostatic equilibrium share a variety of unusual characteristics. One characteristic of a conductor at electrostatic equilibrium is that the electric field anywhere beneath the surface of a charged conductor is zero. If an electric field did exist beneath the surface of a conductor (and inside of it)‚ then the electric field would exert a force on all electrons that were present there. This net force would begin

elGauss’ Law AP Physics C Electric Flux Let’s start be defining an area on the surface of an object. The magnitude is “A” and the direction is directed perpendicular to the area like a force normal. A E Flux ( or FLOW) is a general term associated with a FIELD that is bound by a certain AREA. So ELECTRIC FLUX is any AREA that has a ELECTRIC FIELD passing through it. We generally define an AREA vector as one that is perpendicular to the surface of the material. Therefore‚ you can
