Ans. Dielectrics are the materials used for charge storage, by polarisation of the molecules. They are also called active dielectrics. The dielectric material increases the capacitance or charge storage ability of a capacitor. Q.2. Mention a few properties of dielectric materials. Ans. The properties of dielectrics materials are – They are non-metallic materials. They have high specific resistance. They have a negative temperature co-efficient of resistance. Q.3. Mention the types of polarisation mechanisms in a dielectric material. Ans. There are four different types of…
