3.2: Rectification
This is current charging the capacitor and it peaks at about 180 milliamps. The total time for the charge phase is around 4 milliseconds. Once the output voltage peaks, the capacitor starts to discharge into the load. During the discharge phase note that the capacitor current''s polarity has reversed.
Electrolytic Capacitor
The filter capacitors for a power supply are typically 100 to 1000 μF. Audio capacitors are usually 10 to 47μF. If the electrolytic capacitor is connected in opposite polarity, the reversed electrolysis forms gas in the capacitor. It becomes hot and may explode. This is a possibility only with electrolytic capacitors. Leakage Current
