Default Current through coils

When I show otherwise, snip, gone without reply.


Sorry, I completely missed it. I'll go back and try
to find it.

Sorry, "A bunch of IEEE PhD's" impresses me less than a handful of the
guys posting here.


Have you looked at the articles on the web pages I posted?
Here's a funny quote, not previous quoted from:

http://www.ttr.com/corum/index.htm

"What frequency did you get in step 5? ... Is the difference
within engineering accuracy ... less than 5%? If the answer
is yes, then you may confidently use lumped-element modeling.
However, if the answer is no, then, from the halls of Valhalla,
old Wotan, himself, is thundering out over the battlements,
'#*@&%!! ... Thor, you dumdum! You CAN'T use lumped circuit
modeling!' ... [The coil has standing waves and is behaving
as a distributed resonator.]"

In case you missed it, here's what Walter Maxwell had to say
about the subject:

"If an inductance is in series with a line that has
reflections, the current will NOT be the same at both
ends of the inductor."

"Consequently, circuit analysis will not work when both
forward and reflected currents are present in a lumped
circuit."
