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.

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.
