Explain the terms used in the microscopic version of Ohm's Law

2. Relevant equations

j=oE

3. The attempt at a solution

Well I know what we have here is the current density within a conductor is equal to its conductivity multiplied by an 'E-field'. But what is this E-field? Is it an external field that acts upon the wire? But if this is the case will the electrons in the conductor not just move in a few microseconds to go back into equilibrium meaning j=0. You could act on it with an varying field but then how would the calculation work out?

Or is E the field inside the conductor caused by the current density?

Thanks
