When we turn on a flashlight, something called an "electric current" begins to happen. Inside the flashlight bulb, the thin filament-wire gets hot because there is electric current in the metal. This current is a motion of something. How fast does this "something" move? This question can be answered.
Inside the wires, the "something" moves very, very slowly, almost as slowly as the minute hand on a clock. Electric current is like a flow of syrup. Even maple syrup moves too fast, so that's not a good analogy. Electric charges flow as slowly as a river of warm putty. And in AC circuits, the moving charge doesn't move forward at all, instead it sits in one place and vibrates. Energy can flow fast in an electric circuit because metals are already filled with this "putty." If you push on one end of a column of putty, the far end moves almost instantly. Energy flows fast, yet an electric current is a very slow flow.
Hope this helps.
