Brief introduction to the working principle of intelligent capacitor

 The principle of capacitor is to store electric energy by storing charge on the electrode, which is usually combined with inductor to form LC oscillation circuit. The principle of capacitor is that the charge will be moved by force in the electric field. When there is a medium between the conductors, the charge movement will be hindered and the charge will be accumulated on the conductor, forming the charge accumulation and storage.

Capacitor is one of the most widely used electronic components in electronic equipment. It is widely used in isolation, coupling, bypass, filtering, tuning circuit, energy conversion, control circuit and so on.

One thing:

The capacitor is similar to the battery and also has two electrodes. Inside the capacitor, the two electrodes are separated and connected to two metal plates separated by the dielectric. A dielectric can be an atmosphere, paper, plastic, or any other material that does not conduct electricity and that prevents the two metal poles from fighting each other.

The metal plate on the capacitor connected to the negative pole of the battery will receive the electrons generated by the battery. The metal plate on the capacitor connected to the positive pole of the battery will release electrons to the battery. After charging, the capacitor has the same voltage as the battery (if the battery voltage is 1.5V, the capacitor voltage is also 1.5V).

2. Primary use:

1. the capacitor is used to store electric quantity for high-speed release. This is what the flash uses. Large lasers also use this technology to achieve extremely bright instantaneous flash results.

2. The capacitor can also eliminate the pulsation. If there are pulsations or spikes in the transmission line of DC voltage, the large capacity capacitor can make the voltage stable through receiving wave crest and adding wave trough.

3. The capacitor can be isolated from DC. If a smaller capacitor is connected to the battery, after the capacitor is charged (when the capacity of the capacitor is small, the charging process can be completed in an instant), there will be no electricity between the north and south poles of the battery. However, any alternating current (AC) signal can flow smoothly through the capacitor. The reason is that with the turbulence of the exchange current, the capacitor is constantly charging and discharging, just like the exchange current is active.

4. Capacitors and inductors can be used together to form an oscillator..
