Default Coils are transmission lines

Velocity = 1 / Sqrt( L * C) metres per second


Well now, W7EL, a pretty smart fellow questioned that equation,
as I remember before a bottle of CA Sutter Home Cabernet Sauvignon,
circa 2001. (Not bad for a 5 year old red.)

Dr. Corum's equation is a mite more complicated involving
fractional powers of diameter, turns per inch, and wavelength
and it closely agreed with my self-resonant measurements.

If we work backwards from Dr. Corum's fairly accurate
VF, can we calculate the L and C of the coil?
