What is the frequency of standard AC power in the United States?

The frequency of standard AC power in the United States is 60 Hz, which is the typical rate at which alternating current systems operate. This frequency has been established as the standard for the country's electrical grid since the early 20th century and is widely used in residential and commercial electrical systems. Utilizing 60 Hz allows the efficient operation of many electrical devices and appliances designed specifically for this frequency. Other countries, like those in Europe, commonly operate at 50 Hz, but in the U.S., the reliance on 60 Hz supports compatibility and efficiency in power distribution and device functionality.
