"Just  reminder, Medhurst C is NOT the isotropic capacitance of a coil.
In the few paper on coils  by Medhurst, that I have read he never
the isotropic capacitance of a coil"

	Quite true.  However, his formulae for the self-capacitance of grounded
coils have worked very well for me in predicting the self-resonant
frequency of TC secondaries.  Usually within a couple of percent, which
is almost to good to be true.
