Conductivity through metals and resistance developed in it
I understand that there is high potential difference and so the current flows. A metal conducts electricity only when it is not stable. So, because of high potential difference we can make a metal to conduct. But what I wonder is in practical usage, why don’t those atoms in the metal which are in bonds with another elements takeup these excessive electrons which are flowing on to it (as current: its flow though metal) and become stable. If it happens so, on usage every conductor should gradually turn into heavy resistive metal.
