Question

What is the polarization produced in sodium chloride by an electric field of V/mm if it has a dielectric constant of 6?​

Answer 1

Answer:

1.Find the capacitance of a layer of Al2O3that is 0.5 m thick and 2000 mm2 of square area ( r = 8.854 × 10–12 Fm–1)

Solution:

Given data:

2.A layer of porcelain is 80 mm long, 20 mm wide and 0.7 µm thick. Calculate its capacitance with r = 6

Solution:

Given data:

3.If an ionic crystal is subjected to an electric field of 1000 Vm–1 and the resulting polarization 4.3 × 10–8 cm2. Calculate the relative permittivity of NaCl. Solution:

Answer 2

Answer:

Dielectric polarization is the term given to describe the behavior of a material when an external electric field is applied on it. The charges in the material will have a response to the electric field caused by the plates.
