Everybody realizes that Cecil. You don't need to explain. You need to
understand.

Your attitude toward AC tells me that you don't realize that, Jim.
An AC source is like a battery that changes its '+' terminal to a
'-' terminal every 1/2 cycle in accordance with a sinusoidal magnitude.
Just because you use a Sharpie pen to mark one terminal of an AC source
as the '+' terminal, doesn't mean the current out of that terminal
is always positive. Good Grief - half the time it's negative!

Hey, you're the one who told the story about the 'hot wire' being the
one that the AC comes out of, not me.

Have you got standing waves on your toaster, Yuri?

It's always standing. Sometimes I use laying on the side if I want warm up
pizza slice. That would make laying waves?

So when waves are standing, they don't go to antenna? Antenna don't radiate?
Cool dude!

See how easy it is to get the flow of current mixed up with the flow of
energy? That's what Cecil's been doing.

Anyway, I enjoy your sense of humor, Yuri.

You apparently would be surprised to know that the "hot wire" in
your house has a negative voltage on it half the time. Current
flows out of the "hot wire" half the time and flows into the
"hot wire" half the time. That's simply the nature of AC.

There's no "hot wire" in a balanced RF transmission line.

There are two batteries and a potentiometer hooked up as shown. With the pot in
the fully ccw position, what does the voltmeter read? Which way is the current
flowing?

With the pot in the fully cw position, what does the voltmeter read? Why way is
the current flowing?

It doesn't take a genius to see that if the pot is turned in a certain repetitive
way, the voltage across the load could be sinusoidal with the current reversing
its direction every 1/2 cycle. There's only two DC batteries and a magnitude pot.
Where's the phase?

Applying for further education:
so what is flowing energy, no current flowing?
This is series! (As freepers would say)

Jim must have just realized that is what he has been doing wrong and
is now blaming me for it. Energy moves from an RF source to an RF load.
Current moves back and forth through the source. Current moves back
and forth through the load. The electrons are not lost from the
system. They just move back and forth coherent with the RF frequency.
Electrons possess charge. Current is the time derivative of that
charge. When the movement of charge changes direction, so does the
current.

Applying for further education:
so what is flowing energy, no current flowing?

If AC current always flows toward the load in one wire of a balanced
transmission line, which way is the current flowing in the other wire?
:-) If it is also flowing toward the load, it is common-mode current,
not differential.

When you cannot present a rational argument, mount an ad
hominem attack? What is it that you disagree with me about?
Do you think AC current doesn't reverse direction every 1/2
cycle?


I think you reverse your argument every 1/2 cycle!

Must be your comprehension going into reverse every 1/2 cycle.
I have been perfectly consistent. Most people just don't
understand that AC current reverses direction every 1/2
cycle and flows backwards just as often as it flows forward.
All they have ever seen is an RMS current arrow pointing
away from the source toward the load. The RMS model for
AC has seduced a whole generation of engineers into
feeling the RMS model dictates reality.
