Hey guys, I have two quick questions: Is the outside of an electrolytic capacitor conductive? (Should I worry about it touching some other circuit components)? I have a 5kOhm potentiometer that for some reason began to smoke once while testing a circuit. I powered off the circuit and tested the potentiometer (the resistance decreased from 0-1.3kOhm). After about an hour I retested the potentiometer and it was at 0-5kOhm again!! I replaced it in the SAME circuit, powered it up, and left it on for about 10 minutes. No smoke and it has worked since. Is this common?
