Question

Differentiate between polar and nonpolar dielectric.

Answer 1

Hint:In this question, firstly revise the concepts for dielectrics. Dielectrics are of two types which are polar and non-polar dielectrics. Now we are differentiating the two. The main difference between the two is the shape.

Complete answer:
Firstly, writing what is dielectric. Dielectrics are electrical insulators that are polarized in the presence of an electric field. When dielectrics are placed in an electric field, no current follows through them because they do not have loosely bound or free electrons which may drift the material. Dielectrics are of two types which are:
-Polar dielectric
-Nonpolar dielectric

Differentiating the types in tabular form:

Polar dielectrics	Nonpolar dielectrics
These are material which have inherent dipole moment	These materials do not have dipole moment.
In presence of electric field, positive and negative charges are separated by small distance.	In presence of electric field, positive and negative charges are not separated by small distance
These materials show the property of polarity.	These materials do not show the property of polarity.
Polar dielectrics are the polar compounds that do not conduct electricity.	Non polar dielectrics are the non-polar compounds that do not conduct electricity.
Shape of these dielectrics are asymmetric.	Shape of the dielectrics are symmetric.
Polar dielectrics are polar.	Non polar dielectrics are non-polar.
Example: ammonia and water	Example: benzene and methane

Note:Dielectrics are the compounds that do not conduct electricity. These dielectrics are found as both polar and non-polar dielectrics depending on the polarity of the molecules. The main difference between the two is polar dielectrics have asymmetric shape and the nonpolar dielectrics have symmetric shape.
