WebFeb 2, 2024 · The electric permittivity ε of a medium is defined as a measure of the electric polarizability of dielectric materials in response to an applied electric field. I usually think of it as a measure of the "resistance" of a medium to the establishment of an electric field in it. In SI units, permittivity is measured in farads per meter (F/m or A 2 ·s 4 ·kg −1 ·m −3 ). The displacement field D is measured in units of coulombs per square meter (C/m 2 ), while the electric field E is measured in volts per meter (V/m). D and E describe the interaction between charged objects. 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 … See more In electromagnetism, the electric displacement field D represents the distribution of electric charges in a given medium resulting … 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 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 Coulomb force constant, $${\displaystyle k_{\text{e}}={\frac {1}{4\pi \varepsilon _{0}}}}$$ 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.
