Many students are under the impression that charge must move very fast through an electric circuit. After all, as soon as a switch is flipped on the car lights, the lights are on. But don't be fooled! The charge carriers that move through the light to immediately light the light were there already. They did not have to migrate rapidly from the battery to the lights to instantly light the light. Rather, as soon as the switch was closed, charge everywhere within the circuit begins to flow. The charge carriers that were in or near the light will instantly light the light.
