Hi there, Cec,

You wrote,
"If the forward current is the same magnitude at both ends
of the coil, there's no change in charge.

If the reflected current is the same magnitude at both
ends of the coil there's no change in charge."

Dunno why you keep reverting back to magnitudes, but I'm talking about
current as a function of time, and have been consistently through this
whole thing. Until you get that straight, there's no point in your
even taking part in this. "Cyclical variation in charge (contained
within a volume)" means that on average the charge stays constant, but
it does not mean that it's constant over some arbitratily short but
finite length of time.

Without the capacitance, without the ability to store charge, a
transmission line, an antenna wire, a loading coil, all of them--would
not have the ability to cause delay. Freespace, without a non-zero
permittivity (capacitance), would allow infinite speed of light. But
all these things DO have capacitance, and they DO have
speed-of-propagation at the speed of light or slower.


Cheers,
Tom
