Permittivity of vacuum unit
Did you know?
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 pl… WebThe permittivity of vacuum is exactly 8.854 x 10^-12 Farads per meter (F/m). The permittivity of air is approximately 1.00059 F/m.
