The permittivity is often represented by the relative permittivity εr which is the ratio of the absolute permittivity ε and the vacuum permittivity ε0 . This dimensionless quantity is also often and ambiguously referred to as the permittivity. See more 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 high permittivity … See more 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 … See more 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 … See more 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 That is, the polarization is a convolution of the electric field at … See more The standard SI unit for permittivity is farad per meter (F/m or F·m ). See more The vacuum permittivity ε0 (also called permittivity of free space or the electric constant) is the ratio D/E in free space. It also appears in the See more Determining capacitance The capacitance of a capacitor is based on its design and architecture, meaning it will not change with charging and discharging.
