Thatâs when you need a fat resistor to slowly drain it
Comment on It's just for testing, promise đ¤

I had an 18 Farad capacitor for a while. Yes, 18 Farads, not microfarads.
Not for wimps, it was similar size to a 40 ounce beer bottle and could weld metal when charged.
If that cap rig is yours for testing purposes, well good luck đ¤

See thatâs âBig Electricityâ territory, I donât go there, it scares me lmao

I forget what voltage it was rated for, but I think it was over 400 volts. I never charged it up to full voltage though, I just used it as a filter capacitor for an 18 volt document scanner.
Why? Well I didnât have a proper 18 volt power supply then, so I just rigged one up by wiring a few random wall-wart power supplies in both series and parallel (donât ask, it was a mess), to get 18 volts. But, as youâd expect with such a rig, the power was rather noisy, leaving me with really grainy scans.
So, entered the 18 Farad bad boy to filter the power. Scans came out much better, but I bet OSHA wouldnât approveâŚ

So you just had that laying around, or you bought it for that purpose?

My dad had a habit of collecting random junk, particularly electronics and appliances, for parts or repair. Iâm not sure what device it was that it came out of, as it was only the base of the device with two of those capacitors and a pretty big transformer.
One of the capacitors failed and started leaking the electrolyte out as soon as I tried testing it, but the other one apparently worked fine at least.
