Alternating Current

Alternating Current
(AC)
  An electric current that reverses its direction at regularly recurring intervals.
  U.S. Dept. of Energy, Energy Information Administration's Energy Glossary
  ***
  A type of electrical current, the direction of which is reversed at regular intervals or cycles; in the U.S. the standard is 120 reversals or 60 cycles per second; typically abbreviated as AC.
  ***
  Flow of electricity that constantly changes direction between positive and negative sides. Almost all power produced by electric utilities in the United States moves in current that shifts direction at a rate of 60 times per second.
  California Energy Comission. Dictionary of Energy Terms
  ***
  Electric current in which the direction of flow is reversed at frequent intervals usually 100 or 120 times per second (50 or 60 cycles per second or 50//60 Hz).
