Hi Art,

Distinguish between what resonates and what oscillates. Passive
circuits do not oscillate even though they support the flow of
alternating current.

If what you state above is correct then I am wrong since basically
what I am descibing is a passive feedback circuitu

Hi Art,

There is no such thing as "passive feedback." Feedback is a property
of active circuit design to serve the purpose of tailoring input and
output characteristics.

You simply have to accept the conventional terms instead of making
your own up. What you describe, and has been pointed out to you by
others here recently is simple "coupling." This is not to say
coupling is simple - well, it is, but in the classic sense of being
fundamental. Coupling can be used to affect input and output
characteristics, as you inappropriately label as "passive feedback,"
but you really need to get a grounding in the fundamentals of this
action. This, of course, leads to the study of fields, and as you may
well appreciate that this is no simple course of study either.
