alternating current
- ∙ an electric current in which the direction of flow of the electrons reverses periodically, such as sawtooth, sinusoidal or square wave current.
- ∙ an electric current in which the direction of flow of the electrons reverses periodically by a sinusoidal law, hence having an average of zero, with positive and negative values (with a frequency of 50 Hz in Europe, 60 Hz in the US, 400 Hz for airport lighting, and some others); especially such a current produced by a rotating generator or alternator.

ENGLISH WIKIPEDIA - THE FREE ENCYCLOPEDIA
Alternating current
Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.
