Question
Provide a brief information about dielectric materials.
✓
Answer
→Non-conducting materials are called dielectrics.
→Dielectrics are of 2 types :
(1) Polar dielectric
(2) Non-polar dielectric
(1) Polar dielectric :
→The type of dielectric material in which the centres of a positive and a negative electric charge do not coincide is called a polar dielectric.
→The molecules of a polar dielectric possess permanent electric dipole moment.
Example : $H _2 O , HCl$, etc.
(2) Non-polar dielectric :
→The dielectric in which the centres of positive and negative charges coincide is called nonpolar dielectric.
→The molecules of a non-polar dielectric do not possess permanent dipole moment. Exa., $H _2, O _2, N_2$ etc.
