Description of real RESISTANCE...

As we know the resistance is potential difference times current. Potential differences between two points produce a force that is called e.m.f that tends to push charges from one point to another. Current is the rate of flow charges per time across the wire.

But what is the real resistance? In my opinion, people with many differences make a huge potential (P.D.), so the society starts changing. And the population of people who are standing for their needs can make a significant current. So when these two grow alongside each other; a significant resistance can be made.
