The four types of polarization which occur in dielectrics are:
(I) Electronic polarization,
(II) Ionic polarization,
(III) Orientation or dipole polarization,
(IV) Space charge or interfacial polarization
Let us discuss them one by one:
(I) Electronic polarization. Electronic polarization occurs due to displacement of the centre of the negatively charged electron cloud relative to the positive nucleus of an atom by the electric field.
Example. Monoatomic gases exhibit only electronic polarization. Continue reading “Types of polarization”
