So I'm sort of confused by voltage and I hope these will clear it up for me; 1) Why can parallel circuits only have equal voltage drops on both sides? Say a voltage of 5 is entering the parallel circuit, and one side uses 5 and the other uses 4, why is that not possible? 2) If voltage is what moves current by giving it energy, how come the current stays the same? Why doesn't voltage dropping it cause it to lessen and even stop near the end of the circuit? Is it cause the current coming in from behind the old current is pushing it? 3) Is voltage just basically charge attracting electrons from one point to another? If not, how is it created? 4) What happens if Kirchhoff's 2nd law is not followed, and all the voltage is not used up by the time the current reaches the end of the circuit and enters the battery? Does it just overheat?
