I agree. Your above posting is just plain stupid. You are stating the
opposite of what I have said hoping some readers will not notice.
Resistors exist *in reality* e.g. in dummy loads. You are promoting E/
I ratios, existing as virtual resistances, to be as real as a physical
resistor. Hopefully, no one ever loads his virtual gun with one of
those virtual resistances and fires it at you. Question is, would you
die or not? It has been said that everyone creates his own reality and
it must be true. You guys have created models of reality in your minds
that bear very little resemblance to the real world.

In the field of optics, an real image that actually exists in reality
is clearly differentiated from a virtual image which is an illusion
that doesn't actually exist where it appears to exist. Light waves are
EM waves. RF waves are EM waves. You guys are promoting a model that
considers virtual images to actually exist at the point where they
appear to exist but are only an illusion. I agree with you - that is
just plain stupid.

To summarize: Resistors, capacitors, and inductors, defined under the
concept of impedors (from "The IEEE Dictionary") are real-world
devices with a physical existence - one can pick them up and touch
them.

E/I ratios, containing resistance plus capacitive or inductive
reactance, are impedances that do not have a physical existence. Their
existence is conceptual and exists only in human minds capable of
concepts (much like the concept of God).

When you are standing four feet from a mirror and your image appears
four feet behind the mirror, you are arguing that you can replace your
actual self with an alternate self four feet behind the mirror and
everything will be exactly the same. I agree with you - that is just
plain stupid.
