Thanks, Tom, for taking the trouble to go through the numbers. As I said
earlier, most of us know, and all engineers certainly should know,
superposition requires that results from an analysis using the total
current must be the same as the sum of the results from separate
analyses using forward and reflected currents (or any other components
whose sum is the total current). Your analysis shows this, as it should.

Roy, would you please explain what is the technical significance
of Tom's superposing the forward wave of 1 amp at zero degrees at
the bottom of the coil with the forward wave of 1 amp at 45 degrees
at the top of the coil when those two currents are separated in
space by 12 inches and separated in time by 45 degrees of a cycle?

Doesn't the superposition principle require the two signals to exist
in the same space-time? The misconceptions being presented here are
unbelievable but apparently exist in the engineering community.
