Question

Is there any electric field inside a conductor carying an electric current?

Answer 1

No there isn't. Use Gauss's theorem.

Answer 2

The electric field is require to have current

Answer 3

Oh wait, i think i must have misunderstood the question..

Answer 4

there must be electric field due to electric source. You cant' use gauss's law because it considers only the electric field due to charged objects, for instance when you take some charged conductor there is no electric field inside the conuctor, but it causes electric field outside that goes through for instance wire and due to this you have current in wire. The battery provides that electric field so that current can go for a long time

Answer 5

oh right..

Answer 6

If the wire were charged you would have electric field due to that charge that is not inside this wire. But the external electric field that goes through wire makes charges moving. In other words the wire may not be charged
