If you are driving this resonant circuit from _another_
loosely coupled resonant circuit, in a perfect world
the voltage would ultimately reach Vs = Vp SQRT(Ls/Lp).

Actually, the frequency content of the current in the
gap is mostly the res freq at low coupling, with some
freq splitting at high coupling. Not much total power
is present elsewhere in its spectrum. An o-scope will
readily demonstrate this.

These are symptoms of success!
