An electrolytic capacitor reversed biased presents
itself as a pretty good short circuit. If the supply
is very strong, it can blow it, but most supplies
have significant resistance when compared to the
capacitor's reverse resistance.

In any case, aluminum electrolytic capacitors are not
as good a fuse as, say, a transistor. It takes them
a little while to heat up and start boiling their
electrolyte.

Hi Chuck,
Thank you.

Was trying to find the 'quote' option...

Have now :)
