    Dielectric constant  of the 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.
    F0/Fm = ε/ε0 = K ……(from Coloumb’s law).
    Physical significance of dielectric constant is the resistivity to stop the current or conduct electricity through material but induces charge on it in electrostatic.
