Lower Resonant Frequency = Longer Sparks //Theory for Solid-State Tesla Coil design

This is my MOSFET-driven SSTC which is of Steve Ward's design (mini sstc 5). Here, I demonstrate the major difference in spark length achievable by having a lower resonance frequency, versus a higher one. This difference is due to a reduction in switching losses in the semiconductor, when switching at lower frequency (I was wrong about that, please read my edit below). EDIT: After asking many different Tesla-coilers online, I realized it's fairly difficult to know exactly why there's an increase in spark length; there could be many different factors attributing to this. Major contributing factors: 1) Lower impedance in primary coil because of lower frequency, therefore, more current. 2) More charge accumulation by secondary's larger C, requiring a higher voltage before discharge can occur. After recording this video, I measured the resonance frequency of the secondary coil for each topload, using a signal generator and oscilloscope: Small topload: f = 318.4 kHz Big topload: f = 229.2 kHz
