CBSE Class 12-science Answered

Dear student,

There are many electric field lines inside a conductor...the reason there is no "net" electric field is because the charges balance themselves in such a way to cancel the overall electric field. If we place "excess" charge on a conductor (excess meaning a charge not associated with the structure of the material itself) and then leave the conductor alone we will observe a net electric field inside the conductor of zero after a very short time period.

The "excess" charge will basically reside on the outside of the conductor and will distribute in such a way as to cancel any net electric field within the conductor. So a conductor that is in "electrostatic equilibrium" will have no net electric field inside the conductor.
