Epsilon Naught Value

1. What does the Epsilon Naught Value mean?

The permittivity of open space is referred to as Epsilon Naught in physics. Moreover, this is a mathematical quantity that illustrates the maximum allowed electric field in open space or a vacuum. Epsilon of water, on the other hand, refers to the maximum intensity of an electric field that can pass through or be allowed to exist in water.

2. What is the value of Epsilon Naught?

The potential of the classical vacuum to admit the electric field is what is meant to be understood by the permittivity of empty space (ε₀). ε₀= 8.854187817 × 10^-12 F.m^-1 (in SI units) or ε₀ = 8.854187817 × 10^-12 C²/N.m² (in CGS units) is the approximate value of Epsilon Naught.

3. Define Permittivity.

Permittivity is the measurement of electric polarisability of a dielectric measured in presence of electric field

4. What is the unit of Epsilon Naught?

• SI Unit of Epsilon Naught is Farad per meter or F.m^-1
• CGS Unit of Epsilon Naught is Coulomb square per Newton meter squared or C²/N.m²

5. What is the importance of Epsilon Naught Value?

The dielectric permittivity of the free space is represented by it. A material’s dielectric constant is determined by taking its value, or Epsilon Naught.

Epsilon Naught Value is 8.85418782 × 10^-12 m^-3 kg^-1s⁴ A². Epsilon Naught is represented as ε₀ where Epsilon is a Greek letter with 0 as its suffix. Epsilon Naught is used to represent the Permittivity of free space and permittivity is basically the measure of the polarisibility of a material in the presence of an electric field.

Permittivity simply means, that the greater the value of permittivity the more a material will polarise in the presence of the electric field. The permittivity of free space is also called the permittivity of the vacuum. In this article, we will learn what is epsilon naught, what is the value of epsilon naught, the dimensional formula of epsilon naught, and its derivation.
