I want to build a coilgun and have come up with a setup for my caps that I think will work but I wanted to make sure before I wire it all together. I was thinking of putting a 35,000V .003uf Maxwell Pulse Cap in series with a 20V 1farad Speaker System Cap. Using the Product Over Sum method for two series caps, .003uf X 1000000uf/.003+1000000, I found that the overall rating for my caps would be 35,020V 333.33uf with an output of, .5 X .00033333 X 35020 squared, or 204,398.0227 Joules. I feel confident that I did this part of my calculations correctly however, I'm not quite sure what my charging voltage should be and I've been having some trouble finding this out so I was hoping you might be able to tell me. Also, if you've found anything that you think may be wrong with my calculations, I be happy to know what they are!
Thanks,
