Let's say I wire the negative pole of a battery to the positive pole. Obviously, the battery will short circuit as the electron pool in the negative side will become attracted to the positive side and cause a huge flow.
However, if I add a lamp to the circuit, the electrons again flow because they are attracted to the positive pole, but for some reason only enough of them to power the lamp. Why don't they keep flowing past the lamp and drain the battery just like a short circuit? Why does the resistance dictate the current?
