Capacitance is the ratio of the change in the electric charge of a system to the corresponding change in its electric potential. The capacitance of any capacitor can be either fixed or variable, depending on its usage. From the equation, it may seem that ''C'' depends on charge and voltage.
The amount of charge that a capacitor can store is determined by its capacitance, which is measured in farads (F). The capacitance of a capacitor depends on the surface area of its plates, the distance between them, and the dielectric constant of the material between them. Capacitors are used in a variety of electrical and electronic circuits.
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
Put your understanding of this concept to test by answering a few MCQs. Click ‘Start Quiz’ to begin! The capacitor is a two-terminal electrical device that stores energy in the form of electric charges. Capacitance is the ability of the capacitor to store charges. It also implies the associated storage of electrical energy.
Capacitor and Capacitance are related to each other as capacitance is nothing but the ability to store the charge of the capacitor. Capacitors are essential components in electronic circuits that store electrical energy in the form of an electric charge.
The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V
Apart from the suitability of different capacitors for specific applications, other important factors that may need to consider include the following: Tolerance – It must be checked if the working of the circuit depends on precision capacitance. A capacitor with the lowest tolerance should be used if it requires narrow capacitance.
