Equation of state¶
In the physics of dielectric materials, the “equation of state” is the equation that connects the electric displacement with electric field strength, temperature, and density of the medium. This equation cannot be determined solely from thermodynamics and must be either supplied from experiment or derived from the theory of dielectric polarization.
