In the last article, I have discussed the dielectrics and polar dielectrics. Today let us discuss the non-polar dielectrics:
Non-polar Dielectrics or Molecules. If the centre of gravity of positive charges coincides with the centre of gravity of negative charges then the dielectric is called non-polar dielectric.
Example. H2, N2 etc.
Thus, a non-polar dielectric has a zero electric dipole moment In the presence of electric field, the charge centres get displaced and dielectric or molecule is then said to be polarized and therefore dielectric acquire an induced dipole moment in the direction of the field.
Note : After reading this article, you will be able to answer the following questions:
What are non-polar dielectrics,
What are non- polar molecules,
Write the examples of non-polar dielectric materials,
Why non-polar molecules have zero dipole moment
