Default Current across the antenna loading coil - from scratch

Actually, the problem is more elementary than coils. Everyone
seems to understand coils installed in circuits.

The ignorance seems to be of the nature of the physics involved
in standing waves, whether on a wire or on a coil or in free
space. So I have switched the discussion to where it belongs,
to a discussion of standing waves, with or without coils,
with or without wires.

I offered the following example which the gurus refuse to touch
with a ten foot pole. One wonders why. The transmission line is
lossless and BB is a black box.

Source-------a-BB-b-----------c-BB-d---------open circuit

The current at 'a' is measured at one amp.
The current at 'b' is measured at zero amps.
The current at 'c' is measured at zero amps.
The current at 'd' is measured at one amp.
What's in the black boxes?

Would you believe ZERO responses from the gurus?



In an Internet discussion, everybody has the right to attempt to switch
the discussion away from the point.

Everybody else has the inalienable right not to follow them.
