Webε r \varepsilon_r ε r - relative permittivity of medium, ε \varepsilon ε - absolute permittivity of medium, ε 0 \varepsilon_0 ε 0 - permittivity of vacuum. Medium permittivity depends on temperature and pressure. Values given in this calculator have been measured at the pressure of 1013,25 hPa and temperature of 20 °C. 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 polarizes more in response to an applied electric field than a material with low permittivity, thereby storing more energy in the material. In electrostatics, the permittivity plays an i…
