most metals make good conductors, so we use metal wires as a path in electric circuits
insulator are opposite of conductors they're materials that electrons have a hard time flowing through
A switch controls the flow of electrons by opening and closing a circuit.
when a switch is in the "off " position, the circuit is openen.
And when a circuit it's in the "on" position, the circuit is closed, and electrons can flow through.
