Sähköpitoisuutta

Sähköpitoisuutta refers to the electrical capacitance of a material or object. It quantizes the ability of an object to store electrical energy in an electric field. More formally, it is defined as the ratio of the electric charge stored on each of two conductors to the difference in electric potential between them. The unit of capacitance is the farad, symbolized by F. A farad is a large unit, so picofarads (pF) and microfarads (µF) are commonly used in practice.

Capacitance is a fundamental property in electrical engineering and physics. It plays a crucial role in various electronic circuits, such as filters, oscillators, and energy storage devices. The capacitance of an object depends on its geometry and the dielectric material separating the conductors. For a parallel plate capacitor, for example, capacitance is directly proportional to the area of the plates and inversely proportional to the distance between them, as well as being dependent on the permittivity of the dielectric material. Understanding sähköpitoisuutta is essential for designing and analyzing electrical systems.
