Answer 2

Ohm's law has sometimes been stated as, "for a conductor in a given state, the electromotive force is proportional to the current produced." That is, that the resistance, the ratio of the applied electromotive force (or voltage) to the current, "does not vary with the current strength ."

Vector Form of Ohm's Law

Jˉ is the current density, Eˉ is the electric field and σ is conductivity. Conductivity is the reciprocal of resistivity.
