Armed with this information, you should try to understand voltage, resistance, relays, and transistors, in roughly that order. That may help to bridge the gap from the water gates here, to transistors which are solid state; you can't see them moving, but they largely accomplish the same basic function and can be used to create the same kinds of gates using just electricity.
