Several responders discussed the Norton or Thévenin equivalent circuits.
These circuits assume steady state conditions, and are intended to be
replacements for groups of components. A very useful concept, but not

Hi Roger,

Quite a bizarre stance. Do you regularly come to these points of view
without further thought, elaboration, or analysis? It seems you have
assigned some remarkable characteristics to the Norton and Thevenin
source and you don't offer us anything substantive beyond what would
be called "Arthur's proposition."

To cut to the chase, Norton and Thevenin sources are appropriate to
network analysis irrespective of your perception. You should look
closer at your issues of difficulty because it does not reside in
their classic application to classic situations.

More later. I as still thinking about the "perfect power source".

That's fine, but it is now turning into a mantra rather than a
productive examination. You would do well to spill your guts as to
why you commit so much of the calendar to this thought. Alone, it is
as meaningful as announcing that one is thinking about "cold fusion."
