Question

The value of the static dielectric constant of any material is always

• A. greater than 1
• B. equal to 1
• C. lesser than 1
• D. None

Answer 1

The correct option is A greater than 1

Dielectric constant or relative permittivity is the materialistic property of any material .Relative permittivity of a material is the ratio of permittivity of the material to the permittivity of free space,

${\epsilon }_r=\frac{\epsilon }{{\epsilon }_0}$

As $\epsilon >{\epsilon }_0$, because permittivity of free space is lowest, therefore ${\epsilon }_r\left(orK\right)>1$
