Since everyone is being a little picky, there is also no such thing as
RMS power. When you use RMS voltage you get average power. :)

Then what do you get when you use average voltage?

IIRC for a sine wave,

VRMS = .707 x peak
VAVG = .615 x peak

Misleading answers.

If you _really_ want to get the actual average power delivered to the
load you need to measure the voltage and current, multiply them and
average (or multiply them, average and measure...). Using voltages
assumes that your load is resistive. Using Vrms = 0.707 * Vpeak assumes
sine waves, etc.
