The dielectric constant of a metal is

What is the dielectric constant of metal ?

The dielectric constant of water is 80. What will be its electrical permittivity?

By inserting a plate of dielectric material between the plates of a parallel plate capacitor at constant potential, the energy is increased five times. The dielectric constant of the material is

If C and C_(0) are capacities of a capacitor with and " without dielectric medium respectively then dielectric constant of medium K is

The space between parallel plate capacitors is filled with four dielectrics of equal dimensions but of dielectric constants K_(1), K_(2), K_(3)andK_(4) respectively. If K is the dielectric constant of a single dielectric that must be filled between capacitor plates to have the same capacitance between A and B. Then we must have

Define dielectric constant of a medium in terms of force between electric charges.

If temperature is increased, the dielectric constant of a polar dielectric decreases whereas that of a non-polar dielectric does not change significantly The magnitude of dipole moment of individual polar molecule decreases significantly with increase in temperature.
