'''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.<ref>http://www1.eere.energy.gov/solar/solar_glossary.html</ref> | '''Alternating current''' (commonly abbreviated '''AC''') is a type of [[electrical current]], the direction of which is reversed at regular intervals or cycles.

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]
