The capacitor capacity is not the capacitance. The capacitance of the capacitor is the nominal parameter of the capacitor, which is unchanged; and the capacitance of the capacitor refers to its ability to store charge, which is related to the voltage at its two ends.

Is the capacitor capacity the capacitance?

Capacitor capacity is not capacitance!

The capacity of a capacitor is the nominal parameter of the capacitor, which is constant; the capacitance of a capacitor refers to its ability to store charge, and is related to the voltage at its two ends. C=Q/U----C, the capacity of the capacitor; Q, the capacitance of the capacitor.

Extended information:

Capacitor, usually referred to as its ability to hold charge as capacitance, is represented by the letter C. Definition 1: A capacitor, as its name suggests, is a 'container of electricity', a device that holds electric charge. English name: capacitor. Capacitors are one of the electronic components widely used in electronic equipment. They are widely used in DC isolation, coupling, bypass, filtering, tuned loops, energy conversion, control, etc. in circuits. Definition 2: Capacitor, any two conductors (including wires) that are insulated from each other and very close to each other form a capacitor.

Capacitance is different from capacitor. Capacitance is a basic physical quantity with the symbol C and the unit is F (Farad).

General formula C=Q/U Special formula for parallel plate capacitors: inter-plate electric field strength E=U/d, capacitor capacitance determining formula C=εS/4πkd With the rapid development of electronic information technology, the development of digital electronic products The speed of upgrading is getting faster and faster, and the production and sales of consumer electronic products, mainly flat-panel TVs (LCD and PDP), notebook computers, digital cameras and other products, continue to grow, driving the growth of the capacitor industry.
