In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (), is a measure of the electric polarizability of a dielectric material.
The definition of capacitance (C) is the charge (Q) stored per unit voltage (V).= Elastance (S) is the reciprocal of capacitance, thus, [1]= . Expressing the values of capacitors as elastance is not commonly done by practical electrical engineers, but can be convenient for capacitors in series since their total elastance is simply the sum of their individual elastances.
In some sources Oliver Heaviside is given credit for coining the term, [2] or with introducing the concept under the name permittance. [3] This claim is mistaken according to Steinmetz's biographer. [4] The term susceptance does not appear anywhere in Heaviside's collected works, and Heaviside used the term permittance to mean capacitance, not ...
Capacitance is the ability of an object 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.
Vacuum permittivity, commonly denoted ε 0 (pronounced "epsilon nought" or "epsilon zero"), is the value of the absolute dielectric permittivity of classical vacuum.It may also be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum.
Synonym list in cuneiform on a clay tablet, Neo-Assyrian period [1] A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. [2] For example, in the English language, the words begin, start, commence, and initiate are all synonyms of one another: they are ...
Thesaurus Linguae Latinae. A modern english thesaurus. A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms ...
Superparamagnetism is a form of magnetism which appears in small ferromagnetic or ferrimagnetic nanoparticles.In sufficiently small nanoparticles, magnetization can randomly flip direction under the influence of temperature.
