In general, permittivity is not a constant, as it can vary with the position in the medium, the frequency of the field applied, humidity, temperature, and other parameters. In a nonlinear medium , the permittivity can depend on the strength of the electric field. Zobraziť viac In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (epsilon), is a measure of the electric polarizability of a dielectric. A material with … Zobraziť viac In electromagnetism, the electric displacement field D represents the distribution of electric charges in a given medium resulting from the presence of an electric field E. This distribution includes charge migration and electric dipole reorientation. Its … Zobraziť viac The linear permittivity of a homogeneous material is usually given relative to that of free space, as a relative permittivity εr (also called dielectric constant, although this term is deprecated and sometimes only refers to the static, zero-frequency relative … Zobraziť viac In general, a material cannot polarize instantaneously in response to an applied field, and so the more general formulation as a function of time is Zobraziť viac The standard SI unit for permittivity is farad per meter (F/m or F·m ).
