Question

The dielectric constant of air is

Answer 1

Dielectric constant:

1. The dielectric constant of a substance may be defined as the ratio of the permittivity of the substance to the permittivity of the free space.
2. This is an expression of the extent to which a material can concentrate electric flux, and it is the electrical equivalent of relative magnetic permeability.
3. It is mathematically expressed as: $K=\raisebox{1ex}{$\epsilon $}\!\left/ \!\raisebox{-1ex}{${\epsilon }_0$}\right.$ where,
4. $K$ is the dielectric constant $\epsilon$ is the permittivity of the substance ${\epsilon }_0$ is the permittivity of the free space.
5. At ambient conditions, the dielectric constant of liquid water is around $78.4$.

The dielectric constant of air is $1.00059$
