This must be a noob question but I will ask anyway:
I have an electrolytical capacitor coupled in series. The + side of the capacitor is connected to 6 Volts of a headphone amplifier circuit output.
With a multimeter I measure the other - side of the capacitor: I measure 6 Volts.
I expected to measure a few mV at most, theoretically 0 Volts. Is this normal behavior due to some voltage leakage and the high impedance of the multimeter?
Almost every capicitor I tried shows this. They cannot all be bad can they?

Normal for a high impedance meter. Put any sort of load on it and it will go down to something reasonable.
I was not sure but you confirmed my suspicion. Like you said, if I put a load of 43 ohm on it DC is practically zero.
Thanks!
