Sorry I am no electronics expert .. but I am surrounded by designers, developers and test engineers when I am at work. Today capacitors were mentioned and the accidents that others have seen, fairly grim I'm afraid! The one thing everyone agreed on was .. do not touch them if you are not qualified to do so. We have them at work and the warning printed on the side of them states 'Death is imminent'. They hold 500,000 volts, even the smallest ones hold 400v.
Sorry but it is not something I would advise anyone about !
