What does capacitor mean? There are capacitors in life.

Capacitor is a standard circuit component, which is simply used to store and release charge. The capacitance that household appliances can touch is nothing more than the capacitance used for motor circuits in household appliances with motors such as fans, washing machines and air conditioners. The electric fan uses about 1.5 microfarads, the price is a few dollars, and the air conditioner uses dozens of dollars. There are also electrolytic capacitors, smoothing or coupling used in electronic circuits, which can generally be seen at a glance, such as computer motherboards and power amplifiers.
