The process of causing a charged capacitor to lose charge (release charge and electrical energy) is called discharge
The process of causing a charged capacitor to lose charge (release charge and electrical energy) is called discharge. For example, use a wire to connect the two poles of a capacitor, and the charges on the two poles neutralize each other, and the capacitor will release charge and electric energy. After discharge, the electric field between the two plates of the capacitor disappears and the electrical energy is converted into other forms of energy.
In general electronic circuits, capacitors are commonly used to achieve bypass, coupling, filtering, oscillation, phase shift, and waveform transformation, which are the evolution of their charging and discharging functions.
The role of the capacitor in the circuit: In the DC circuit, the capacitor is equivalent to the open circuit. A capacitor is a component that can store electric charge and is one of the most commonly used electronic components.

The process of charging a capacitor (storing charge and electrical energy) is called charging
The process of charging a capacitor (storing charge and electrical energy) is called charging. At this time, the two plates of the capacitor are always positively charged, and the other plate is negatively charged by the same amount. One plate of the capacitor is connected to the positive pole of the power supply (such as a battery pack), and the other plate is connected to the negative pole of the power supply, and the two plates are respectively charged with the same amount of dissimilar charges. After charging, there is an electric field between the two plates of the capacitor, and the charging process stores the electrical energy obtained from the power supply in the capacitor.

A capacitor is composed of two electrodes and a dielectric material between them.
A capacitor consists of two electrodes and a dielectric material between them. Dielectric material is a kind of dielectric. When placed in the electric field between two parallel plates with equal amount of opposite charge, polarization charge is generated on the surface of the medium due to polarization, so that the charge bound on the plates increases accordingly, maintaining the potential difference between the plates unchanged. This is why the capacitor has a capacitive characteristic. The amount of electricity Q stored in the capacitor is equal to the product of the capacitance C and the potential difference U between the electrodes. The capacitance is proportional to the plate area and the dielectric constant ε of the dielectric material, and inversely proportional to the thickness of the dielectric material (I. e., the distance between the plates).
