Dielectric constant of dry soil is

A. 3 - 6

B. 4 - 23

C. 20 - 30

D. None of the above

Answer: Option A

Solution(By Examveda Team)

The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux and is the electrical equivalent of the relative magnetic permeability.
The dielectric constant of dry soil varies between 3 - 6 depending on the texture of the soil.
