Q. What is dielectric polarization?
The arrangement of the dipole moments of the permanent or induced dipoles in the direction of applied electric field is called polarisation or electric polarisation. The magnitude of the persuade dipole moment p is directly proportional to the external electric field E.
∴ p α E or p = α E
Where α is the steady of proportionality and is called molecular polarisability.
