Current through coils

Hi Cecil, I just today found the (QRZ.com) discussion. I agree
with your position 100%. It's as simple as this:
If an inductance is in series with a line that has no reflections,
the current will be the same at both ends of the inductor.
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.
When reflections are present, a current node and a current loop
can appear at separate points on an inductor simultaneously.

I think it would be better if Walt represented himself, unless he ASKED
you to post that Cecil.
Why not let Walt post what he thinks rather than someone else telling
us what Walt thinks? We each should speak for ourselves and let other
people speak for themselves. If Walt has something to say, I'm sure he
will chime in.
Drumming up support by writing what we **think** others say or mean
seems pretty desperate.
All of that aside, what does it matter who agrees or disagrees? Things
work they way they work. All reliable measurements I've seen disagree
with Cecil's theory.
I can't believe anyone with experience in RF systems would think a
physically small inductor (small in terms of wavelength) would have
significantly unequal currents in the inductor or in the terminals of
the inductor, especially any difference caused by "reflected waves".
