Is there any electric field inside a current carrying conductor?

On applying an electric field of 15 xx 10^(-6) vm^(-1) across a conductor , current density through it is 3.0 Am^(-2) . The resistivity of the conductor is .......

Heat produced in a conductor of resistance 4.2Omega with 10A current is _____ cal/sec

The ratio of magnitude of current density and magnitude of electric field inside the conductor is

The ratio of magnitude of current density and magnitude of electric field inside the conductor is

Assertion: Drift velocity of electrons developed in a current-carrying conductor is of the order of 10^(-4) m//s but current in the conductor is established almost instantly the switch is closed. Reason: Electric field in a conductor sets up with the speed of light.
