Hmm--It's strange for me to be the voice of reason, but if you can't analyze an LCR circuit, you have no business messing around with one at this sort of power level. Well, even if you can analyze an LCR circuit, you have no business messing around with one at this sort of power level unless you have been trained by a professional. It's easy to get yourself injured or dead if you don't know what you're doing (e.g. electrocution, exploding capacitors, "splash", etc).
