so what happens to all the stored energy? dissipated by heat?

and as for why my computer died (power on, screen off) usb is not connected there's no shared link, it's isolated,
My guess is that the high-voltage arced back throught the power supply into your house-power, causing a power-line spike.

Exploding caps can easily take out an eye or two.


I've got a couple of 68000uF caps on the shelf. They look at least 20 years old, maybe more. We used to hold a couple of wires on them to charge them up then melt nails across the screw terminals on the top. Stuff like that. Here's one of them with a couple of normal size components for comparison.



One day a little 10uF electrolytic exploded quite close to me. The metal case flew across the room fast enough to flatten itself against the opposite wall (which means it must have been going about the speed of a bullet...)

Ever since then I've been too scared to charge the big one.

No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

Heat+light+sound. A bit like an electric firecracker.

I have only come here seeking knowledge. Things they would not teach me of in college.
