Gary -

I agree with what you have said about RMS power. What do you think about the
3 KW to 1700 KW power gain I mention in another post? Do you have any
comments regarding the Instantaneous power gain of Tesla coils?

Sorry to pick nits, but a recent reference to RMS power set me off, rather
like fingernails on a slate blackboard.  Our meters measure measure average
voltage and current on the dc ranges, rms voltage and current on the ac
ranges, but only AVERAGE power (never RMS power). Average power is the
product of rms voltage, rms current, and power factor. It is possible to
mathematically define a quantity called rms power, but it has no physical
meaning that I know about.
