Is the aluminum shell of electrolytic capacitor charged?

Charge. According to the inquiry of Shenzhen Tongsheng Times Technology Co., Ltd., there is a capacitor between the aluminum shell of electrolytic capacitor and the two poles of capacitor, so the shell is basically charged normally. Electrolytic capacitor is a kind of capacitor. The metal foil is the positive electrode, the oxide film near the positive electrode is the dielectric, and the negative electrode is composed of conductive materials, electrolytes and other materials. Electrolyte is the main part of cathode, so electrolytic capacitor is named.
