Does an electrolytic capacitor degrade each time it receives reverse voltage?
I know that I mustn't connect an electrolytic capacitor reversely. It will explode if I apply the reverse voltage long enough.
But, what happens if the reverse voltage is applied for a short time? ...

Electrolytic Capacitor Voltage Rating vs capacitance
I have always believed that it was ok to replace a capacitor with a slightly higher voltage rated one. eg 16v with 25v.Going higher than this would risk the capacitance value being out at the working ...

Avoiding electrolytic capacitors in high-pass filters with sub-Hz cut-off
We need to design a HPF filter to AC couple a bipolar signal to a high gain amplifier. Any substantial DC left would saturate the amplifier, and thus it must be removed with the high-pass filter(HPF)....
