Electric current...

Homework Statement

When a steady current passes through a cylindrical conductor , is there an electric field inside the conductor?

Homework Equations

The Attempt at a Solution

How do i approach this...? I mean i know -E.dx = dV in electrostatics...So going by that here current is flowing so there is ome potential difference and so there should be a field given by -V/x ehre V is PD and x is length of wire...IS this right?

yes there is electric field.
this is very simple as if there was no field ... why would the electrons move to produce current?
