1)Define with units
1)Electric dipole moment.
2)Polarizability
3)Electric susceptibility
2)Explain the following properly-
1) Polarization
2) Ferroelectricity
3) Pyroeletricity
3)What do you mean by polarization in dielectric material. Hence differentiate types of Polarization Namely ionic & orientation.
4)Write a short note on polar & non-polar
dielectric material with their examples.
5)What is dielectric loss? explain with a suitable phasor diagram & derivation.
6)Derive clausius moscotti relation as applied to dielectric materials in static field. State the assumption made.
7)Explain loss tangent. with a neat diagram explain the method of finding the tan delta value of insulating material
8)Write a note on piezoelectric materials stating their applications.
