Question

How the net charge in a current-carrying conductor is always zero?

Answer 1

Electric current is the flow of free electrons in the conductor. At any instant, the number of electrons leaving the wire is always equal to the number of electrons flowing from the battery into it. Hence, thenet charge on the wire is zero.
