Dimensional Formula of Permittivity (Free Space or Vacuum) The dimensional formula of Permittivity of free space or vacuum is given by, M-1 L-3 T 4 I 2. Where, M = Mass; L = Length; T = Time
The dimensional formula for permittivity of free space (ϵ 0) in the equation F = 1 4 π ϵ 0 q 1 q 2 r 2 where, symbols have their usual meaning is [ M 1 L 3 A − 2 T − 4 ] [ M − 1 L − 3 T 4 A 2 ]
Following is the table with the mathematical representation of permeability, SI unit, and dimensional formula: Mathematical representation \(\begin{array}{l}Permeability=\frac{Magnitude\;of\;magnetic\;induction(B)}{Intensity\;of\;magnetic\;field(H)}\end{array} \)
The permittivity of free space: The vacuum characterizes the least possible permittivity value. This is called the Permittivity of Free Space or electric constant. The dimensional formula for permittivity of free space: F = 1 4 π ε 0. q 1 q 2 r 2 ⇒ ε 0 = 1 4 π F. q 1 q 2 r 2; Dimensions of F = [M L T-2] Dimensions of q = [A T] Dimensions ...
The permittivity is often represented by the relative permittivity ε r which is the ratio of the absolute permittivity ε and the vacuum permittivity ε 0 = = . This dimensionless quantity is also often and ambiguously referred to as the permittivity.

5 days ago · The dimensional formula of Permittivity of free space or vacuum is written as M 1 L-3 T 4 I 2 where M stands for mass, L stands for length, T stands for time, and I stands for a charge. Derivation of the Dimensional Formula of Relative Permittivity
Permittivity ( ϵ ϵ, F/m) describes the effect of material in determining the electric field intensity in response to charge. In free space (that is, a perfect vacuum), we find that ϵ = ϵ0 ϵ = ϵ 0 where: ϵ0 ≅ 8.854 ×10−12 F/m ϵ 0 ≅ 8.854 × 10 − 12 F/m.
The permittivity defined by Equation \ref{1.5.3} is known as the “rationalized” definition of the permittivity, and it results in much simpler formulas throughout electromagnetic theory than the “unrationalized” definition.
The dielectric constant, known as the permittivity of a material, is discussed on this page. This property of a material slows down the propagation of light and reduces the wavelength. The units are Farads per meter.
