Web5 Answers. An easy way to prove Ohm's law for electric fields that aren't constant is to first assume that the electric field is approximately constant over short lengths, just like E = d V / d L suggests. Using that, you can derive Ohm's law for short lengths of material, d V = I d R. We'll assume that "current in = current out", which is true ...
