Your right!!  That is why I put in the disclaimer to forgive screw ups :o)))

Cheers,

Hi Terry,

If the time is say 100pS. Resistance is gone and only inductance of the path matters as Jim says. If we arc a few inches to another large sphere of considerable capacitance then the inductance of the arc path might be say 100nH. Ipeak = Vp x SQRT (L / C) == 108000 x SQRT(100nH / 31pF) == 6.1 million amps!!!

Ipeak = Vp / sqrt (L/C)  ?????      (1900 amps assuming Vp =108000)


What is a "light curve"?

Intensity of light vs time, I think in this context.
