Question

Define dielectric constant of a medium and write its formula. ​

Answer 1

Answer:

The Dielectric constant (K) of the medium is the ratio of the permittivity of the substance (\varepsilon) to permittivity of the free space (ε0). i.e K=ε/ε0. As Permittivity of medium and permittivity of free space both have same units(F/m ie Farad/meter) dielectric constant becomes dimensionless quantity.
