Solution

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.
