Hello. I am new to a lot of this, so I want to make sure I got this 
correct. Did I do this right to find the peak current when the spark 
gap fires? Assuming the only inductance in the calculation is the 
primary coil....

Surge impedance = sqrt(Lp / Cp)      my primary is around 48.029uH 
according to calculations, and capacitor is 
0.01uF    so  sqrt(0.000048 / 0.00000001F) = 69.282     and then 
current peak = Vp / Surge impedance  so  12000 / 69.282   = 173.205 
amps?   This is most likely way wrong :P
