In a couple of threads watts has been refered to as volts x amps = watts ! I thought that was for DC voltage and for AC it is volts x amps x power factor = watts .

You are Correct!
Yes indeed.
The general, and correct, formula for power is voltage x current x power factor.
In DC circuits that are used to power resistive loads, the PF = 1.There was an error rendering this rich post.

power factor
My understanding is that (power factor correction ) is not used in resistive loads, In a 3 phase suppl. heater circut we add the following amps = KW x 1000 divided by volts x 1.73. On page 17 of the Ugly's book I believe they are talking about inductive, reactive loads. (motors , transformers ) I always like to get several sets of eyes on all questions.There was an error rendering this rich post.
