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." -- 73, Cecil, w5dxp.com |

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 |

Why are you trying to pick an argument? As my mother would have said, "You would argue with a fence post". -- 73, Cecil, w5dxp.com |
