Answer 1

If you're asking about alternating current electricity, check out Wikipedia's article: http://en.wikipedia.org/wiki/Alternating_current

It would be easier to answer more specific questions (are you talking about generation, distribution, conversion, use, or what).

If you're asking about air conditioning, Howstuffworks has a great primer:

Answer 2

Do you mean AC electric current, or do you mean Air Conditioning?

Power distribution utilities use AC (Alternating Current) because it is easier to distribute using wires, easier to change voltages, and more convenient to generate.

The complexities of an AC electric distribution network are far too extensive to discuss here. It takes a shelf of textbooks and reference books to do the subject justice.

Try an internet search on "electric distribution."

On the other hand, if you mean "Air Conditioning," the answer is that it is a machine that uses the principles of condensation and evaporation to remove heat from the air that circulates inside the house and exhaust the heat to the outside air.

Air conditioning is usually abbreviated "A/C" to distinguish it from AC electric current.

Again, the principles and practices of air conditioning are very extensive knowledge, and cannot be covered here.

Try an internet search on "air conditioning."

Answer 3

It works just exactly the same as any other AC power source.

AC is used since it is easy to convert from one voltage level to another by using transformers. Transformers cannot work with DC since they require a time-varying magnetic field to induce a voltage in their secondary windings..
