Specifically, Volts and Amps would be called VA or volt amps, as in the rating of a transformer, but it is loosely referred to as Watts. In DC theory, Volts mulitplied by Amps equals Watts. In AC theory, that same equation exists but it includes power factor. If the power factor given is 1 (100%), then Volts mulitplied by Amps multiplied by Power Factor of 1 equals your Watts.
