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 ...
By definition, a perfect vacuum has a relative permittivity of exactly 1 whereas at standard temperature and pressure, air has a relative permittivity of ε r air ≡ κ air ≈ 1.0006 . Relative permittivity is directly related to electric susceptibility (χ) by = otherwise written as
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.
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.
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
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.
The synonyms are grouped into synsets with short definitions and usage examples. It can thus be seen as a combination and extension of a dictionary and thesaurus . While it is accessible to human users via a web browser , [ 2 ] its primary use is in automatic text analysis and artificial intelligence applications.
A thesaurus or synonym dictionary lists similar or related words; these are often, but not always, synonyms. [15] The word poecilonym is a rare synonym of the word synonym. It is not entered in most major dictionaries and is a curiosity or piece of trivia for being an autological word because of its meta quality as a synonym of synonym.
