WebThe permittivity of a medium describes how much electric field (more correctly, flux) is 'generated' per unit charge in that medium. It is clear that more the permittivity of a matter, more resistance is offered to the electric field resulting in decrease if the flux in Gauss law. In other words Flux in inversely proportional to permittivity. Permittivity as a function of frequency can take on real or complex values. 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). 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 from the presence of an electric field E.
