Although the deformation of the electron orbit is independent of temperature, the electronic polarization and thus dielectric constant ε of a dielectric with increasing temperature decreases, because increases its volume and decreases the number of particles per unit volume. Thus, the resistivity should increase with increasing dielectric constant.

thank you very much sir. but give me the Mathematical relation to the Dielectric constant and DC resistivity

The dielectricc constant depends on resistivity according to equation: Log R (293K)= 23-2e (293K)

thank you very much for your response

Hojjat, can you point to where you got "Log R (293K)= 23-2e (293K)"? I'd love to understand this.

Hjjat, could you mention the reference of this equation "Log R (293K)= 23-2e (293K)"

 please??

tan (d) = 1/ (wErP)

tan(d) represents the losses

w=2*(pi)f

Er= dielectric constant

P= electrical resistivity

 thank you for your responsr Dear Zainal Nurbaya
