Several standards exist around the world for electrical power distribution. In addition to the obvious physical connector differences (plugs and sockets), AC electric power can be delivered at differing voltage and frequency.
Canada, Mexico and the United States all use a 100–127 volt, 60 hertz electrical system, (as do some other central and South American countries), which shares the same physical connectors.
Most of Africa, Asia and Europe use a 220–240 volt, 50 hertz electrical system, with a variety of differing physical connectors.
