I am builing a coilgun, and was looking into getting more powerful capacitors. i am using a normal photoflash charger, and 10 parallel wired flach capacitors. The capacitors i was looking into getting, are from radioshack, 1000uf 35v or 50v. Would my flash charger still work with these capacitors, or would i need to get a new charger? also if i get ten of these and wire them together, it would still have 10000uf and 350v right? that could come to 1250J energy stored.

You can have 10000uF with a working voltage of 35V (parallel connection) OR 100uF with a working voltage of 350V (series connection). You can't have it both ways!

oh my appologies. i am a little new to this. the bank i am using now is made of 10 330v 120uF caps. and i charge it to 600v. what would you recommend that i do?

i just built a new capacitor bank, out of 18 photoflash capacitors. I lost some power from the gun. Could anyone tell me why that happened, and how i could fix that problem? Would increasing the coil wire size help?
