WebApr 12, 2024 · Capacitance (C) can be calculated as a function of charge an object can store (q) and potential difference (V) between the two plates: C = q V. Q depends on the surface area of the conductor plates, while V depends on the distance between the plates and the permittivity of the dielectric between them. Capacitance is the capability of a material object or device to store electric charge. It is measured by the change in charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual … See more In discussing electrical circuits, the term capacitance is usually a shorthand for the mutual capacitance between two adjacent conductors, such as the two plates of a capacitor. However, every isolated conductor also … See more A common form is a parallel-plate capacitor, which consists of two conductive plates insulated from each other, usually sandwiching a See more Any two adjacent conductors can function as a capacitor, though the capacitance is small unless the conductors are close together for long distances or over a large area.
