In an electric current there must be forces that push electrons in a general direction (current). My question is, what creates this force (electromotive force)?
I assume that this force, that moves electrons, is created by a surplus of electrons in one area. Perhaps they move because the electrons get too close together and push each other away. In a wire, those electrons get pushed through because it's the most accessible path.
If that is the case, then a positive terminal is not required for a current to flow. The positive terminal can't move, so it can't be a factor in the movement of electrons at the other end anyway. All that is needed is a bunch of electrons in one spot.
Am I on the right track?
