Electric field intensity 'inside' a wire carrying current

  1. Aug 4, 2012 #1
    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[/PLAIN] [Broken] law: [itex]\mathbf{J} = \sigma \mathbf{E}[/itex]
