Capacitor charging is connected to the positive pole
A capacitor is a passive device that stores energy in the form of an electric field. When needed, the capacitor can release the stored energy to the circuit. The capacitor is composed of two. The charging process is the process in which the capacitor stores the charge. When the capacitor is connected to the DC power supply, the charge on the metal plate connected to the positive. The discharge process is the process in which the capacitor releases the stored charge. When the charged capacitor is in a closed path without power, the charge on the negatively charged metal plate will be transferred to the positively charged metal under the action of the electric field force, which neutralizes the positive and negative charges,.
