# BPS Formula?

```Original poster: "tmoore by way of Terry Fritz <twftesla-at-qwest-dot-net>" <tmoore-at-erie-dot-net>

Hello all,

I have been messing around with excel and trying to figure out new
things. So I am wondering if I got this right for a static spark gap, Joules
in tank circuit=1/2*(0.000000001*Cap)*Volts^2 where cap is in nano farads.
and volts is what the spark gap is set for.  So say you had a tank cap of
60nf and the gap was set at 17000V you would get Joules=8.67 is this right.
so to figure out the bangs per second it would be power input/joules. so say
you have a power in put of 3kva would you get about 346BPS right????? So any
ways if you can tell me if this is right or tell me how to figure it out
then thanks! Also if you had a rotary spark gap with barley any space
between the flying electrode and the stationary electrode that fired 350BPS
with a tank cap of 60nf and a power input of 3Kva you would get 17kv in the
tank circuit right? Thanks for any help!

Sincerely,
Nolan Moore
