What is the Value of Permittivity of Free Space?
The value of Permittivity of free space is approximately 8.85×10-12 farads per meter (F/m).
Permittivity of Free Space is also sometimes expressed in terms of its inverse, known as the vacuum permeability (μ₀), which is related to the speed of light (c) in a vacuum:
c = 1/ε₀μ₀
Where,
- c is the speed of light in a vacuum.
- ε₀ is the vacuum permittivity.
- μ₀ is the vacuum permeability.
SI Unit of Permittivity of Free Space
The SI unit of Permittivity of free space farads per meter (F/m) in the International System of Units (SI).
Other than this, C2N-1m-2 is also unit of Permittivity of Free Space.
Dimension of Permittivity of Free Space
The Dimension of Permittivity of free space is M-1L-3T4I2.
Permittivity of Free Space
Permittivity of Free Space or Permittivity of Vacuum is the property of material that measures the material’s ability to resist the formation of an electric field within it or to permit the passage of electric flux in a vacuum, as the resistivity offered by the free space is the lowest.
Permittivity of Free Space is introduced to students in class 12. In this article, we will explore the concept of Permittivity of Free Space in detail, including its definition, value, and formula.
