Thevenin and Norton are equivalent circuits	Reply

A most distinguished eham Elmer writes that Thevenin and Norton are equivalent circuits, not laws. Questions: Are the Thevenin and Norton circuits more likely to be used in LF, HF, VHF, or UHF rigs, and why? Which of the two circuits, Thevienin or Norton, are better suited for lower frequency solid state oscillators and which is better suited for high powered tube rigs?

"Which of the two circuits, Thevienin or Norton, are better suited for lower frequency solid state oscillators and which is better suited for high powered tube rigs?" It really all depends on the nascent circuit coercability with respect to the the Poynting tensor field as per the covariant reentrance equations on the voltage-current pseudomanifold. When kalfonic portrusions exceed the pfreedlic (camophryal) saliftrude conditioned on the trace of the impedal matrix, the transfer metafunction can develop unscrubbable Polifan-Sarori singularities. The Thevenin circuit is more suited for that condition. If the transfer metafunction's inverse reprisal matrix foliation can be apluded analytically and forcibly, the Norton circuit may be more appropriate. However, colfornial sompination screeds filliatron fomestery nombludent on the gratofierous sompf. 73, Bof

Actually McAfee and Norton are equivalent circuits and either will work with solid-state or tubes.

In "Fields and Waves ...", Ramo and Whinnery give a warning that applies to both Thevenin and Norton equivalent circuits: "It must be emphasized, as in any Thevenin equivalent circuit, that the 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

N3OX: "It really all depends on the nascent circuit coercability with respect to the the Poynting tensor field as per the covariant reentrance equations on the voltage-current pseudomanifold." No it doesn't. N3OX: "When kalfonic portrusions exceed the pfreedlic (camophryal) saliftrude conditioned on the trace of the impedal matrix, the transfer metafunction can develop unscrubbable Polifan-Sarori singularities. The Thevenin circuit is more suited for that condition." You're just saying that.. N3OX: "If the transfer metafunction's inverse reprisal matrix foliation can be apluded analytically and forcibly, the Norton circuit may be more appropriate." Only if the particular design of the interocitor and flux capacitor require it. N3OX: "However, colfornial sompination screeds filliatron fomestery nombludent on the gratofierous sompf." Now THAT I agree with! 73 de Jim, N2EY

Thevenin can't hold a candle next to Norton, BSA, or Triumph.

Holy cow, I did not know there is a user ID "drolltroll." Now I'll have to find another adjective for "funny." How about, uhm, "funny?" Yeah. That oughta do. What do those Poynting vectors poynt to anyway? (Yeah, I know. That joke is old and lame. I couldn't resist.) Now let's see who can hijack this thread the fastest and we can discuss some more movie reviews...

"Are the Thevenin and Norton circuits more likely to be used..." You know this already, but they are not used anywhere, not even homebrew rigs. This might be a good April 1st prank. Go to Radio Shack or Fry's and ask to see the Norton and Thevenin circuit boards.

It's Not Polite to Poynt	Reply

"What do those Poynting vectors poynt to anyway?" That's a trick question. Of course they don't poynt to anything. They poynt away! Is this the right forum for an argument? 73 de Jim, "I've got movie sign!" N2EY
