Question

Explain the difference between polar and non-polar dielectric materials.

Answer 1

Polar dielectrics: Polar dielectrics are those in which the possibility of center coinciding of the positive as well as negative charge is almost zero i.e. they don’t coincide with each other. The reason behind this is their shape. They all are of asymmetric in shape. Some of the examples of the polar dielectrics are $N{H}_3,HCl$, water etc.

Non-polar dielectrics: In the case of non-polar dielectrics the centres of both positive, as well as negative charges, coincide. Dipole moment of each molecule in non polar system is zero. All those molecules which belong to this category are symmetric in nature. Examples of non polar dielectrics are: methane, benzene etc.
