Dielectric Properties of Solids

Dielectric Properties of Solids: A solid which does not allow the net flow of electric charge on applying an electric field (in spite of presence dipoles) is called a dielectric solid. It is because the electrons are held strongly by individual atoms in insulators and do not move in an electric field. However, due to shifting in charges, dipoles are produced which result in polarisation. Two possibilities in which the alignment of dipoles occur are- Depending upon the alignment of dipoles, the crystals have very interesting properties such as-
