Re: [TCML] Spherical topload SGTC



Maibe the gap acts as a variable capacitor. I suppose that for very big toploads there will be some little inductance (from the connection tap to the margins of the topload), so the variable sphere gap cancels this weak inductance so the topload will be seen by the driver tesla coil as purely C.
