1,200 Amps

I wanted to look at the current flowing into the coils from the coil powersupply.

I passed the coil current through this ammeter shunt resistor. 100 mV =  100 A.

With the capacitors triggered at 400 V, we see a > 1,200 A current spike lasting about 10 ms:

That’s some current!!!

Those capacitors ought to be covered with a piece of Plexiglas or something. You could get a lethal shock from them very easily.

I’ll do that today!

It would only take a dropped spanner or screwdriver across that capacitor bank buzz-bar to blow up the whole lab … I’ve tried to tell him before.

[…] Previously I measured 1,200 amps going through the coils with the capacitors charged to 450V. […]
