How do different capacitor leakage current occur?

The capacitor medium cannot be absolutely non-conductive. The capacitor is applied with a DC voltage, the capacitor will have leakage current(LC). Electrolytic capacitor The two poles of the electrolytic capacitor are made of a dense insulating film that is electrochemically formed with an insulating medium in the middle. There will be leakage current when voltage is [...]
