Question

Obtain SI unit of absolute permittivity

Answer 1

Answer:

Si unit of absolute permittivity C^2/N-m^2.

Answer 2

The SI unit of absolute permittivity is Farads per meter (F/m).

Absolute permittivity:

Absolute permittivity is a physical constant that describes the ability of a vacuum to permit the formation of an electric field.

it is used in determining the behavior of electric fields and their interaction with matter.

It is denoted by the symbol ε₀. Mathematically, it can be expressed as

                               ε₀ = D / E,

where

D = electric flux density

E  = electric field strength.  

The SI unit of electric flux density is coulombs per square meter (C/m²), while the SI unit of electric field strength is volts per meter (V/m).

Therefore, the SI unit of absolute permittivity can be obtained by dividing the unit of electric flux density (C/m²) by the unit of electric field strength (V/m). This gives the unit of Farads per meter (F/m).

Hence,

The SI unit of absolute permittivity is Farads per meter (F/m).
