Alternating current or AC electricity is different from the DC electricity you get from batteries, in that it moves back and forth instead of flowing directly through the wire. AC is the electricity we have in our homes, which powers our television, lights and computers.
Alternating Current or AC electricity is the back-and-forth movement of electrons in a wire, similar to a back-and-forth sloshing of water in a hose. When the force of a negative (-) charge is at one end of a wire and a positive (+) potential is at the other end, the electrons in the wire will move away from the (-) charge, just like in DC electricity. But if the charges at the ends of the wires are suddenly switched, the electrons will reverse their direction.
