## electric field intensity 'inside' a wire carrying current

I am new here and asking question for the first time of course. My question is very simple. Does electric field intensity exist 'inside' a wire carrying current? Please explain the answer.

Yes. Wherever there is a current density there is an electric field given by Ohm's law: $\mathbf{J} = \sigma \mathbf{E}$
