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.

Subject: RE: [AMPS] Watt meters and PEP
? RMS is equivalent DC heating ability. For example, with a
sine-wave,
200w-pk would have the heating ability of 100DC watts. .
