50 volt disc. Where did my signal go? Took the cap out and measures 4The interesting thing is that this cap wasn't really "shorted". Part of what threw me off for a while during this whole process is that the 110V supply is really low-current compared to what I'm used to, so a tens of milliamps count.
As for ceramics, a physical crack opens all sorts of ways to build up aFascinating, the bit about whisker-growth.
Personally, I have never had a good visual show. Had some stinkersThe 465's cap didn't have enough to be noticeable. However, I have seen some really exciting things -- like balls of white fire from exploding IGBT's powered by a few amps at 300 VDC. Never anything really exciting from a capacitor, however, most of the unfortunate electrolytic experiences were much more sedate than usually described.
