AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions. (Your lights will light up regardless of the direction of the electron flow.) A lot of people think of electron flow as electrons moving along a wire freely like cars go down a highway. Actually, it works a little differently. Any conductor (thing that electricity can go through) is made of atoms.
