"As far as elementary textbooks are concerned, we have no name for the thing which flows inside of wires. Yes it's true that this entity, whenever it is flowing, is properly called "an electrical current." But when the stuff *stops* flowing, what do we call it? It's still inside the wire of course. But it's not moving anymore. Refer to advanced physics texts, and there we'll find its correct name: Charge. An electric current is a flow of charge. Yet the K-6 books never mention this. Instead they say that "current flows." They say it over and over. And over! And any students are very lucky if they avoid picking up the wrong idea that the charges vanish when the flow is halted. (Does the water in a pipe suddenly evaporate when you halt its flow? No, and neither do the flowing charges within a metal wire. The "current" is gone, but the charges just stopped in place.)"
