So I have one last roadblock to understanding how circuits fully work and it has to do with currents (in series). To my current understanding, if we were to have a simple DC circuit with one battery at 10V and one resistor at 10 ohms, the current at all points in the wire is 1 A. Now, if we were to connect another resistor of 10 ohms, the current would be then be .5 A. I am essentially trying to figure out how is the current determined in the wire before it encounters any resistors. What I don't understand here is how is it possible for the electrons to know what speed to travel with when it doesn't know the resistances that are ahead of it? Shouldn't as much charge as possible be trying to escape the terminal of the battery regardless of the resistors ahead? If the way I'm explaining it doesn't make any sense, I will gladly offer up a different explanation. Thanks!
