The polarization in dielectric refers to 

The polarization in dielectric refers to  Correct Answer Orientation of the dipole moment in the direction of applied electric field.

Correct option-1

Concept:

Dielectric

  • Dielectric is a material that does not have a free charge carrier for conduction. They however contain positive and negative charges which are bound together. 
  • They can be easily polarized which means charges inside the material will show response to an electric field applied externally.
  • Dielectric materials are used to store energy. These materials exist in solid, liquid, and gaseous forms. Some examples of dielectric materials are:
  1. Solid Dielectrics – Plastic, Ceramic, Glass, and Mica
  2. Dielectric Liquid – Distilled Water.
  3. Dielectric Gas – vacuum, nitrogen, Dry Air,  and helium.

 

Explanation:

  • Polarizability- It is the tendency of an atom's electron cloud to be distorted from its normal shape by the application of an external electric field.

Properties of Dielectric material

  • The band energy gap in the dielectric materials is very large.
  • The coefficient of temperature for resistance is negative.
  • They have high resistivity.
  • They have a strong attraction between electrons and the parent nucleus.
  • They have a very low electrical conductivity of these materials.
  • That's why they are basically electrical insulators.
