Question

What are the functions of a dielectric in a capacitor?

✓

Answer

A dielectric material between the plates of a capacitor
1. increases the capacitance of the capacitor
2. provides mechanical support to the plates
3. increases the maximum operating voltage, i.e, the maximum voltage to which the capacitor may be charged without breakdown of the insulating property of the medium between the plates.
