In most households and industrial settings, the standard frequency of alternating current (AC) power is 50 or 60 Hertz (Hz), depending on the region.
In many parts of the world, including Europe, Asia, Africa, and Australia, the standard frequency is 50 Hz.
In North America and some parts of South America, the standard frequency is 60 Hz.
This frequency determines the rate at which the direction of current flow alternates, which is essential for the operation of electrical devices and power distribution systems.
