a: Circuit ~
b: turning on a pump

What: "The fluid-pressure, electrical-potential connection has one very important difference. Connecting a battery to close a circuit is like turning on a pump. Before a circuit is closed with say a switch, no current flows because the pump/battery is effectively not turned on. Any time a battery is connected in a closed circuit is "turned on" unlike a water pipe system in which the pump can be turned on and off even if the pipes make a complete circuit."
