Current through coils

Once again this indicates you are not familiar or comfortable with
basics, and have gotten ahead of yourself by going off somehwre in a
land of reflected waves. Now you are confused, and can't make sense of
basics.
The generator sees a reactive load. When the generator sees a reactive
load, current and voltage are no longer in step. This is true all
through the system from source to load.
3.) You also claim significant current phase shift exists between the
terminals of a compact inductor operated well below self-resonance.
Please define "compact" in terms of the number of degrees
of phase shift measured using a traveling wave.
Phase shift in what Cecil? This is how people get in trouble, make
misstatements, and wind up blaming others for what they say. Here we
are again, trying to work traveling and standing waves into a system
too small to have anything stand when another significantly better
analysis method would easily explain it all.
You keep trying to define the "inductor" in terms of degrees related to
standing waves like standing waves change the properties of the
component. I can't remember the last time I called to order an inductor
and they vendor asked me "what phase shift in degrees of standing wave
100uH inductor do you want?".
It's very simple to measure current and voltage and the phase
relationships in a two terminal device and prove you are wrong.
I've got many technical references that disagree. If you can do
that, why haven't you done that?
I have done it and told you how, you ignore it. Roy has done it and
told you how, you ignore it. I'm sure many thousands of people here and
everywhere else understand in a reactive system voltage and current are
not in phase. I'm equally sure many thousands of people, including
lurkers here, understand a small inductor operated well below
self-resonance has equal phase current entering one lead and leaving
the other.
The only way to get confused on that is if someone doesn't understand
behavior of the basic component, gets in over his head and confuses
himself trying to use a tool that doesn't work, and then lashes out at
others and refuses to listen.
The current flowing into one end and out of the other end of a small
lumped inductor operated far below self-resonance is essentially equal
in both phase and amplitude.
Please define "small" as the number of degrees of phase shift
measured using a traveling wave.
There you go again! Back to traveling and standing waves.
You say it isn't, I say it is, and I can
prove it beyond any doubt to any open minded person.
Here, you are just out and out lying since I never said that.
Want to bet $1000 that you can prove I ever said that? I didn't
think so. What is with this compulsion you have to lie about
what I have said? Can't you win a technical argument without
lying?
There you go again, back to the lowest form of debate. If you can't
understand something or get trapped, just call the other guy a liar.
You very clearly said current in each terminal of the inductor has a
different phase shift several times in your posts.
I say I can easily build a loading coil that acts the same way. I can
replace 40 or 60 degrees of electrical height with an inductor that has
virtually no phase shift in current between the two terminals, and
virtually the same current level. I can prove that also.
I seriously doubt that. Please measure the phase shift using a
traveling wave through any coil that accomplishes that function.
I suspect you are being fooled by the current loop located inside
the coil and the fact that you have been ignorantly been measuring
the net standing wave current which is essentially irrelevant.
I can't understand what you are saying or what your point is, other
than you think I am being fooled by standing waves, I am ignorant, and
anything I measure is irrelevant.
Maybe someone else can help me with your last statement.
I'm just not sure I can prove anything to someone who thinks a current
transformer measures current that doesn't flow!
I explained it to you, Tom, in another posting. If you don't
understand it, you need technical help. At a fixed point on a wire
(where no net current or net charge is flowing) that is experiencing
a constant exchange of H-field energy with E-field energy every
cycle, a toroidal pickup coil will certainly report the results of
that orthogonal energy exchange between the fields even though there
is no lateral flow of net current or net charge. That's why a
standing-wave dipole radiates broadside and a traveling-wave
dipole is an end-fire.
Maybe someone else on this group can explain or understand what you are
trying to say.
Anyone help me here? What is Cecil saying in that last paragraph? What
does the pattern of a radiating structure in the far-field have to do
with current in a circuit with a reactor?
