Electricity Miscoceptions Spread by Textbooks

"In metals, electric current is a flow of electrons. Many books claim that these electrons flow at the speed of light. This is incorrect. Electrons actually flow quite slowly, at speeds on the order of centimeters per minute. And in AC circuits the electrons don't really flow at all, instead they sit in place and vibrate. It's the energy in the circuit which flows fast, not the electrons. "
