Default Current through coils

Cecil,

This is getting more interesting by the moment. Have you now removed
some of the well-known physical attributes of wire and transmission
lines? Specifically, what happened to the L and C of the wire?

I have no issue with the use of network theory, reflection coefficients,
standing waves, or any other commonly used descriptions. However, none
of these mathematical conveniences change the fundamental physical laws.
If current, and therefore charge, appears to be unbalanced, then there
must be charge storage somewhere.

As Reg pointed out, the charge is stored in the capacitance of the coil.
No need to invoke any magic incantations about networks and standing waves.

In principle any of these problems can be solved with very basic
equations found in any E&M text. In practice it is extremely cumbersome
to do so, and that is why all of the network formulations have been
developed. Just don't fall into the trap of thinking that any new
physical behavior is created by the reflections and standing waves. I
believe in previous messages you have referred to that thinking as
"seduced by the math models."

Your response makes no sense at all. Unequal currents into and out of
a passive black box implies charge storage, which generally means
capacitance.



Boundary condition: There's nothing but wire inside the black box.
