Electrostatics of a Conductor #8211; (i) On its surface any excess charge given to a conductor will appear, (ii) When the net electric field inside the material of conductor will be zero, to an uncharged conductor is placed inside an external electric field, (iii) The electric field on the surface of a charged conductor will be perpendicular at every point. (iv) The electric potential inside the material of a charged conductor is always constant, (v) The electric field at a point near to the surface of charged conductor = σ/ε<sub>0</sub>, where σ = Surface charged density at that point.
