Permittivity, also called electric permittivity, is a constant of proportionality that exists between electric displacement and electric field intensity. This constant is equal to approximately 8.85 x 10-12 farad per meter (F/m) in free space (a vacuum). It is the measure of resistance of a medium in an electric field, it is denoted by Greek letter epsilon (ε) More litrelly ,it defined as the “amount of charge (q) needed to generate one unit of electric flux”. 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.
