Electric field inside conductor

  1. Apr 23, 2010 #1
    When we connect a battery across a loop of wire having some finite resistance there comes into picture an electric field E which is empirically given by J/sigma.(sigma==>conductivity).
    but how can there exist an electric field inside a conductor??We had already learnt that electric
    conductor inside a conductor is zero.please explain.
    (reference griffiths -- electrodynamics)

    That's only true for the case of electrostatic equilibrium. When you apply fields and have moving charges, that statement no longer applies.
