A steady current is flowing in a cylindrical conductor. Is there any electric field within the conductor ? If yes, what is its relation with current density?

Text Solution

Verified by Experts

Yes, an electric field existes within the conductor because it is the electric field which provides acceleration to electrons for the flow of current.
