Capacitor is one of the basic components of the electric circuit, which can store electric charge in the form of electric potential energy. It consists of two conducting surfaces such as a plate or sphere, and some dielectric substance (air, glass, plastic, etc.) between them.
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.
Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance which depends entirely on the geometry of the capacitor (the physical configuration of conductors).
A Capacitor is a two terminal electronic device that has the ability to store electrical energy in the form of electric charge in an electric field. It is a physical object. It consists of two conductors generally plates and an insulator (air, mica, paper, etc.) separated by a distance.
Basic Structure: A capacitor consists of two conductive plates separated by a dielectric material. Charge Storage Process: When voltage is applied, the plates become oppositely charged, creating an electric potential difference. Capacitance Definition: Capacitance is the ability of a capacitor to store charge per unit voltage.
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.
