What is Permittivity of Free Space?
The resistivity offered by the free space is the lowest and is the fundamental constant, it is referred as permittivity of free space and is denoted by ε₀. It has a value of 8.85×10-12 Farad/meter.
The permittivity of free space, often denoted by the symbol ε₀ (epsilon naught), is a physical constant that represents the ability of a vacuum or free space to permit the transmission of electric field lines. Its value is approximately 8.85×10-12 farads per meter (F/m) in the International System of Units (SI).
Vacuum Permittivity Definition
Vacuum permittivity is a fundamental physical constant that characterizes the ability of a vacuum (empty space) to permit the electric field lines to propagate through it.
Vacuum permittivity or permittivity of free space is denoted by the symbol ε₀ (epsilon naught), and it plays a crucial role in the formulation of Coulomb’s law and Maxwell’s equations, which describe the behavior of electric fields.
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.
