I understand the concept of a current, and how current is defined by the amount of coulombs passing through a point in the circuit, per second.
What I'm confused about is when it comes to parallel circuits, and how currents are not constant.
If current is the rate of which charge flows, do speeds of the electrons matter on how many they are. For example, can't a group of 0.5 coulombs of charge flow as fast a 1 coulomb of charge? Why is current dependent on the number of coulombs? It's kinda like a drop of water running down a pipe as fast as a stream of water. So what really is current....?
And since voltage is proportional to current, does that mean it is also proportional to charge (amount of coulombs). So a higher value of coulombs will result in a higher value of voltage...?
Apologies in advance if I sound like a neanderthal.
