a.c.
Summer climate control
A.c. is an abbreviation for alternating current, the type of electrical current that periodically reverses direction—as opposed to d.c. (direct current), which flows one way.
A.c. is the standard form of electricity delivered to homes and businesses: The outlet provides 120-volt a.c.
Also written AC or ac.
