Question

The dielectric constant decreases if the temperature is increased. Explain this in terms of polarization of the material.

Answer 1

Answer:

On increasing temperature, the random motion of molecules or dipoles increases due to thermal agitation and the dipoles get less aligned with the electric field and thus dipole moment decreases.

Answer 2

We can say that temperature rise results in reduced polarization and dielectric constant reduction

Explanation:

• The sum of polarisation can only be understood as the degree to which a dielectric's molecules are precisely aligned with an actual electric field.
• The more the molecules are associated with the actual magnetic field, the larger the polarization and the larger the dielectric constant.
• Nevertheless, with temperature rise, the molecules ' thermal agitation or randomness increases in their interaction with the ground.
• Therefore, we can assume that temperature rise results in reduced polarization and dielectric constant reduction.
