Subject: safe capacitor discharge times ?
Was thinking today, Electrolytic capacitor and current ratings. Of course if
you wack a screw driver across it, will discharge faster than capacitor
rating (10amps is about as good as I have seen, maybe 1amp for smaller
values), capacitor will be damaged in anycase trying to give a large high
peak amp pulse, could heat up or even explode...
so onto my question, if I have a pulse of 100amps, but the rise time is only
1amp per uS, instead of a 100amp rated capacitor, could a 1amp one be used
instead ? It would in effect draw 1amp for 100uS for example but has passed
100amps in total.
