n
(Electrical Engineering) a continuous electric current that periodically reverses direction, usually sinusoidally. Abbreviation: AC Compare: direct current

al′ternating cur′rent


n.

al·ter·nat·ing current

(ôl′tər-nā′tĭng)
An electric current that reverses its direction of flow at regular intervals. Because the voltage of alternating current can be easily controlled with transformers, this is the type of electricity generated by power stations. The transformers raise the voltage to make it easier to transmit over long distances, then lower the voltage for safer use in homes and buildings. Compare direct current. See Notes at current, Tesla.

alternating current

A rapidly reversing electric current.
