As usual, zero technical content from you.

Tom, here's a "circuit" for you.

+--------------------------------+

source Load
| |
+--------------------------------+

The source is delivering 200 watts in the form of V=100V and
I=2A in phase. The load is 4050 ohms. Using your circuit model,
you assert that the current through the source is equal to the
current through the load since it is a series circuit. Yet, if
the current through the 4050 ohm resistor were actually 2.0A,
the power to the load would be about 16,000 watts, thus violating
the conservation of energy principle.

Is there a current drop from the source to the load? Of course!
Does this violate Kirchhoff's laws? Of course not!

Why doesn't your circuit model work? Because the wires
between the source and the load are 1/4WL of 450 ohm ladder-line
thus rendering the circuit model invalid for the application.

YOUR CIRCUIT ANALYSIS MODEL DOES *NOT* WORK ON DISTRIBUTED NETWORK
PROBLEMS!!!

You still don't get it, Cecil, which is o.k. since I didn't expect you
to. I don't doubt that Yuri can find a coil that exhibits a different
current at one end than at the other; I have an antenna that exhibits
the same behavior, and I made it that way on purpose. However, the
term "current drop" as used by Yuri was wrong. There is no place for
it in electromagnetic theory, and if you had known enough theory to
understand that, you wouldn't have answered as you did.
