When the electric field intensity becomes larger, the charge storage capacity also becomes larger, and the quantity representing the electric field intensity is the electric field intensity E of the capacitor. The smaller the distance between the conductor plates, the greater the electric field strength. When the capacitor is connected to the power supply, the charge of the power supply flows into the capacitor. At the same time, an electric field is formed between the conductor plates, and the intensity of the electric field is also increasing until the limit value of the capacitor is reached, and no new charge enters the capacitor. When the capacitor is saturated with charge, the electric field strength formed between the conductor plates reaches a maximum, and the capacitor can store energy. When the amount of charge stored in the capacitor reaches the maximum value, the power supply is disconnected from the capacitor, but the previously stored charge can be maintained. When the power supply is reconnected to the capacitor, the stored charge begins to be released.
