Hello, about two weeks ago I bought a box o' capacitors from electronic goldmine because I read some good reviews and I wouldn't mind having some extra capacitors lying around. I currently play around with electronics at home; making circuits, tearing things apart, etc. My issue is that when I started to sort out this box of capacitors, I found that a lot of them were broken to my knowledge. Every time I hook my capacitor up to a particular capacitor, there would be no reading. The funny thing is that it seems to be certain types of capacitors that aren't being read and then there is other types that are working fine.
To get to the point, my question for you guys is should every type of capacitor be able to be read with a multimeter? I suspect there might be certain types that can't be detected by a multimeter. Below are some of the capacitors that did not read a value?
A side question: I received 10 paper-in-oil capacitors that say 0.068(uF presumably), but they read like 0.080uF. Is that kind of tolerance expected? (Yellow thing in picture)
Side Question #2: There was 3-4 different types of ceramic disc capacitors. They said things on them like R2R1, R4R7, R3R9. There was nothing that showed the capacitance, just numbers like this: R2R1, R4R7, R3R9. The weird thing is when I plug them into my multimeter, which has a 4000uF max, it shows OL. Something seems fishy, so is this normal or is this an indication of the capacitors being bad?
Thanks for your time.
