How about "average power" the correct term.


_________________________________________________ ________

This will be the third time I've asked for an official source for this
"correct" term. If there is no reply, I shan't be asking again.



References:

Same one I gave before in an earlier post.
2000 ARRL handbook 6.6 chapter 6, RMS VOLTAGES AND CURRENTS. Read on
to the pep power paragraph too.

Here is another:
Here are quotes directly from: Electronics Pocket Handbook by Daniel
L. Metzger. Page 13.
This is a nice little book if you ever run across one pick it up.
About 280 pages.

Peak, Average and rms.

1. Use peak voltage or current to calculate maximum instantaneous
power only.

2. Use average current to calculate average power when the voltage is
fixed dc. Use average voltage to calculate average power when the
current is unvarying dc.

3. Use rms voltage and /or rms current to calculate average power when
the load is a linear device (resistor) and both V and I are ac in
phase and of the same waveshape. Use IV, I^2 R, V^2/R.

4. Rms measure is assumed in any ac voltage or current notation unless
peak, peak to peak, or average is specified.

5. The factor .707 for converting peak to rms applies to sine waves
only.
