How to debug capacitor overvoltage
I''m curious to know, if an electrolytic capacitor is charged using a current source, at some point near its maximum allowed voltage, it will start drawing a large leakage current, so the voltage could stabilize, at a point, if the current feeding it is small enough. Afterwards, what happens...
