Default Current through coils

Nor do I. Tom was not making a case for inequality of current in and out
of a coil either. He was just making an inaccurate statement.

Cecil has a good case. Straight wire and coiled wire have the same
properties, only more or less of them. When they are in the path of a
traveling wave and a reflection of that wave comes back from the
opposite direction, they respond similarly. An interference pattern
exists on the coil as it does on straight wire if the distance is
comparable to a wavelength. Superpositon makes both volts and amps vary
along the route.

So, indeed the current at one end of a coil in that situation can be
different at from that at the other end, the same as it would along a
wire.

Distributed network theory is newer than lumped network theory but both
have been around plenty long enough to be well established. I don`t
think Cecil is breaking any new ground.
