What is the difference between dielectric and insulators?
Insulators | Dielectric |
1.Insulators opposes the flow of electric charges | 1.While dielectrics stores the electric charges. |
2.They cannot be polarized. | 2. They can be polarized when they placed in an electric field. |
3. A strong covalent bond exists in the insulators. | 3. A weak bond is exist in the dielectric as compared to insulators. |
4. Their electrical conductivity is very low or zero. | 4. When a dielectric material is kept in an electric field, the charges do not start flowing like in conductors, instead, electron clouds and the nucleus get shifted slightly in the opposite directions. |
5. The value of dielectric constant is quite low. | 5.They have high value of dielectric constant. |
