Solution
Dielectric used in capacitors:
- Dielectrics are used in capacitors because dielectric reduces this tendency more than an air gap.
- All its materials are insulators and good dielectric material can be polarized.
- The electric field between the capacitors polarizes the surface molecules of the dielectric material.
The diagram of the dielectric capacitor is given below:
