I'm just a CE with an unhealthy interst in mechanical and electromech stuff. :P

Discharge time is regulated by the time constant, which in turn is defined by the overall circuit's resistance and capacitance and the nature of the electrolyte. I can't remember the exact formula. But I do know to fear anything that is measures it's max wattage with five or six (or more) figures. I've had lighting strike within a hundred meters of me, that wasn't fun. Having lighting strike within me, NO WAY! <img src="/images/graemlins/smile.gif" alt="" />
