alternating current, AC
A type of electrical current, the direction of which is reversed at regular intervals or cycles.

In the United States, the standard is 120 reversals or 60 cycles per second. Electricity transmission networks use alternating current because voltage can be controlled with relative ease.

Alternating current is easier to transmit over long distances than direct current (DC), and it is the form of electricity used today in most homes and businesses.
