Alternating current (commonly abbreviated AC) is a type of electrical current, the direction of which is reversed at regular intervals or cycles. That is, it has a non-zero frequency, as opposed to direct current (DC), which has a zero frequency. In the United States, the standard is 120 reversals or 60 cycles per second. Electricity transmission networks use AC because voltage can be controlled with relative ease.[1]
