    Dielectric constant : The dielectric constant of a medium is the ratio of the electrostatic force of interaction between two given point charges held certain distance apart in vacuum/air to the force of interaction between the same two charges held the same distance apart in the material medium.

    Now, the capacity of parallel plate capacitor filled with air is given by
