An alternating current changes position 50 to 60 times per second due to the changing charges at the ends of the wires. As the charges change from (+) to (-) and vice versa, the electrons in the wire change direction according to its attraction and repulsion from the charges. Whether a country uses 50 or 60 depends on its electrical system.
