Default Current through coils

That is true but having zero standing wave amps at one end
of a coil and one standing wave amp at the other end doesn't
mean the charge is changing.

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.

The standing wave current is the sum of those two phasors.
That sum is what is fooling you. Please pay attention to
Hecht, in "Optics".

The standing wave current profile does not move through
the wire just as the standing wave light profile does
not move through space.

Standing wave current doesn't progress through a wire just
as standing wave light doesn't progress through space.



It sure would be nice if were as simple as all that. We wouldn't
need NEC to help us if it were. You're missing the point, Cecil,
read Tom's post again, and meditate on this Ch'an buddhist koan
that I just made up in my head: Is the water the wave?
