I belive it is Air Conditioning. A related intellectual curio of note, which may be instructive, is the brou-ha-ha surrounding the titular meaning of legendary hard-rock outfit AC/DC. While boffins have suggest rather lugubrious uses of the acronym, including 'After Christ, Devil's Children', and the like, the band insists that the appellation was culled rather prosaically from the lettering found on electrical equipment, which they insist means 'Alternating Current/Direct Current'. If (and only if) storied rockers AC/DC are correct, the 'AC' about which you query must stand for 'Alternating Current'.
If you're meaning AC as in Electricity then you're talking about Alternating Current. There are normally symbols on Electronics or Computers.
The two forms of Electricity are AC and DC. AC Stands for Alernating Current and DC stands for Direct Current. AC electricity comes out of the Powerpoint that your computer is probably using and DC electricity is used in 5.1 voltage batteries that probably power your flashlight or toy.
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
An ac motor cannot generate electricity but its shaft can be coupled to that of certain devices like an alternator to in order to generate electricity.
