If the circuit is not linear in those terms, then you cannot form a
valid Thevenin equivalent circuit, and discussion of the Thevenin
equivalent series source impedance is a nonsense... it cannot be used.

Quoting "Fields and Waves ...", by Ramo and Whinnery, "... the
(Thevenin) equivalent circuit was derived to tell what happens *IN THE
LOAD* under different load conditions, and significance cannot be
automatically attached to a calculation of power loss in the internal
impedance of the equivalent circuit."

Yes, that is quite correct Cecil, and nothing that I have written says
or implies or is intended to mean otherwise.

However, your own words in another post
(news://news.bigpond.com:119/c8b7540a...oglegroups.com)

"A 60 Hz Power Generation Plant operates at high efficiency, not at the
maximum power transfer point. If they were 50% efficient, they would go
out of business."

demonstrates that whilst you apparently can quote from text books, you
do not necessarily understand what you are quoting. You do talk nonsense
sometimes!

Owen, my reference supported what you said! Why are you trying to pick
an argument? As my mother would have said, "You would argue with a
fence post".
