Default Re: Wireless Self-Resonance Experiments

Al,

Those Knight glow tube experiments are really interesting.

I was wondering, since I'm not a Tesla coil builder, would there be any in value in adding an external capacitance across the coil, which dwarfed the winding's distributed self capacitance, to produce a fundamental resonant frequency with less energy spread into the overtones. Though the the peak voltages across the coil would then be lower of course, but that could be compensated for with more drive/excitation.

Or is this idea just regarded as a practical problem for Tesla coils because of the high voltage rating required for any lumped tuning capacitors ?

Hugo.
