Default Current through coils

Absolutely NOT! You said the phase difference between the two ends is
45 degrees. Therefore, charge "input" and "output" is balanced ONLY
twice during a cycle, when the instantaneous currents are the same. No
phase need apply he we're talking INSTANTANEOUS currents.


Give us a break, Tom. Of course, we are *NOT* and never have been
talking instantaneous currents. All currents ever discussed concerning
this subject have been RMS currents. That's just your instantaneous
strawman. Long term charge accumulation is averaged over many cycles.
There is simply none of that because the traveling waves are not storing
any net charge inside the coil. How can you get so desperate as to play
such silly games?

My statement obviously meant: One amp of RMS forward current is flowing
into the coil and one amp of RMS forward current is flowing out of the
coil. Average charge is balanced.

Even though the standing wave current is different at each end of the
coil, the average charge into and out of the coil is still balanced.
