[AMPS] Watt meters and PEP

[Dave D'Epagnier]

A 200w peak signal into a 1 ohm load would have a voltage amplitude of
14.14volts. The average power would be Vrms squared / R or 100v/1ohm =
100Watts. This is average power, which is the dc equivalent heating ability.
Power (unlike voltage or current) is always positive. There is no reason or
need to evaluate it's rms level.

	€  RMS is  equivalent DC heating ability.  For example, with a
sine-wave, 
	200w-pk would have the heating ability of 100DC watts.  .
