Well. The answer you gave is exactly the answer I would have given, but
you say my answer is wrong.

I understand about deriving the RMS power from the instantaneous power
in the same way that RMS voltage or current is derived, I just don't
accept the definition. It's been taught the other way all my life, even
though you say it's incorrect. I see your point, I just don't accept
it.

I agree. On the one had we've had a pillar we'd always accepted

that sincerely and I do respect your point of view.

As I'm sure we all do. If this is a misconception it must be an
extremely widespread one. I've found a reference to RMS power and how
it's calculated in 'Practical Radio Frequency Test & Measurement'
(Newnes) and have posted the relevant page he
