This is exactly the same mistake that Dr. Best made. *VOLTAGE DOESN'T RULE!*
Current is *equally* important to voltage. If you had assumed that "current
rules", you would be saying - "when the currents are 180 out of phase it
defines an open circuit".

My argument is actually a minor point but bridges part of the gap between
you and Dr. Best. (And absolutely nothing being discussed here concerns
the source impedance of a transmitter. All we are discussing is what
happens at a match point in a transmission line or at a tuner.)

Then how can you explain what happens when you reverse the zip cord, plugging
one end in one way and the other with the prongs reversed ? Are you saying the
currents in this condition are seeing an open circuit?

I'm sorry, Walt, you lost me. What zip cord?

A point offered that is not even half a day old... Symptoms of two
conversations running under the impression they are on the same
planet.

Cecil, you must not be reading my posts. Go back one or two to get the drift.

Are you talking about the two generators hooked up back to back.
If so, where are the two EM waves traveling in the same direction
which is a prerequisite for complete destructive/constructive
interference? The generated EM waves, in your example, are moving
in opposite directions which is simply not relevant to this discussion.

Please conjure up an experiment where two coherent waves are
moving in the same direction without affecting the generators.
