Default Current through coils

The velocity factor of the coil is based on those quantities
and can be calculated.



What's the formula, Cecil? Also, what is the dominant mode
of a single wire, loading-coil transmission line: TE, TM,
TEM, or what? If not TEM, how do you calculate the cutoff
frequency? If I terminate one of these things in the
right impedance will it act like an infinite transmission line?
Given your loading coil terminated in a given impedance, what is
the expression for the impedance looking into it? I suppose you also
have something that will tell us how to find your coil's characteristic
impedance; o.k., out with it. All this bluster and threatening rhetoric
aren't advancing the acceptance of your crackpot theory one inch, Cecil.
I don't see anything wrong with at least attempting to characterize a
loading coil as a transmission line as long as the attempt is done
dispassionately with real theory and an acceptance of the possibility
of failure as part of the effort. Desperately thinking up excuses for
an idea you made up in your head, and becoming emotionally distraught
when people don't buy those excuses, is a waste of your time and
everyone else's.
