In an explanation of a textbook's diagram it says : "Conservation of charge requires that whatever charge flows into the resistor at point A, an equal amount of charge emerges at point B. Charge or current does not get “used up” by a resistor. So the current is the same at A and B. " I can understand the conservation of charge but isn't current = charge divided by time? Wouldn't the resistor SLOW the charge move, isn't the reason we use them in the first place? So, how come the current is the same at A and B? I'd expect at B the current would be less as resistor would limit the charge passing through itself over time t ?
