i dont know the RMS current... I do know the peak current was about 800A
You can roughly estimate the RMS current from the peak current:
Irms ~= Ipeak*sqrt(burst length/period between bursts)*(1/sqrt(2))
So if your peak current was 800A, your burst length was 250us, and your
breakrate was 120Hz, the RMS current would be about 90A.
This formula holds for spark gap coils too but the constant is nearer 1/2
than (1/sqrt(2))
