Epsilon Naught Value Epsilon Naught is synonymous to the permittivity of free space or absolute permittivity or electric constant, represented by the Greek alphabet ε 0. The Epsilon Naught value is constant at any part of the universe. It is often miss-used as the value of Epsilon not. Permittivity is the measure of the opposition offered against the formation of an electric field.

Permittivity and Permeability Permittivity and permeability are two different measures used in electromagnetism. Permittivity measures the ability of a material to store energy within the material. Permeability is a measure of the ability of a material to support the formation of a magnetic field within the material. Table of Contents • • • • • • • • • What Is Permittivity? Permittivity is the property of every material, which measures the opposition offered against the formation of an electric field. It is represented by the Greek alphabet ϵ. It tells the number of charges required to generate one unit of electric flux in the given medium. Following is the table for permittivity mathematical form and SI unit: Mathematical expression \(\begin \) SI unit of permittivity Farad/metre The vacuum characterises the least possible value of Permittivity. This is commonly referred to as the Permittivity of Free Space or electric constant, which is denoted by ϵ 0 and has the value 8.85✕ 10 -12 Farad/metre. The opposition against the formation of \(\begin \) Where, • ϵ 0 is the electric constant • ϵ r is the relative permittivity • ϵ is the absolute permittivity of that material Using Coulomb’s law, The magnitude of the electrostatic force between two point charges q 1 and q 2 separated by a distance r in free space can be calculated using relative permittivity(ϵ r). By taking “the ratio of electrostatic force(F a) between two point charges separated by a certain distance i...

In the rationalized metre-kilogram-second (mks) and SI systems, the magnitude of the permittivity of a vacuum ε 0 is 8.854 × 10 −12. Its units and those of permittivity ε are square coulombs per newton square metre. In the mks system, permittivity ε and the dimensionless dielectric constant κ are formally distinct and related by the permittivity of free space ε 0; ε = κε 0. In the centimetre-gram-second (cgs) system, the 0 is chosen arbitrarily to be 1. Thus, the permittivity ε and the dielectric constant κ in the cgs system are identical; both of them are dimensionless numbers. This article was most recently revised and updated by
