(clears throat ready to talk-like-a-physicist). It is remarkable how the magnitude of voltage has reduced by one - 50,000 volts in this article, 500,000 in the Daily Mail article versus the 200,000 mentioned on my site. In fact we are all wrong. The peak voltage generated from a Tesl coil can be predicted by the ratio of inductances in a linked resonant system multiplied by the primary coil peak voltage. This is provided there is no load. Once the sparks start breaking out and a load develops in a chaotic manner, then there is no fixed value in what is a highly chaotic waveform which is modulated by the mains 50Hz, spark gap of 1400 BPS and system resonance of around 100kHz. The peak voltage may be considerably lower and depends in all likelihood on cosmic ray ionisation locally as a significant influence on spark directions and initiation. But lets not bring celectial muons into the equation, lets just call it 200kV. (Oh and by the way, that's me) Ahem.. (clears throat ready to talk-like-a-physicist).
