It includes dielectric properties of insulating materials (dielectric constant, dipole moment, polarization, polarizability), mechanisms of polarization (electronic, ionic and orientational), clausiusmossotti equation, piezo, pyro, ferro electric materials, insulating materials and their characteristics, classification, solid insulating materials (paper press board, fibrous, ceramis, mica, asbestos), liquid materials (oil, varnish, askarel), gaseous materials (air, SF6), dielectric breakdown (primary & secondary ionization of gases), magnetic materials (types, applications), description, conducting materials (copper, aluminium), alloys, nanotechnology (energy bands, nano-structures, nano tubes), testing of materials (tangent of dielectric loss angle by schering bridge, dielectric strength, voltage blushing, flux density) etc.,

Paper Pattern:Question paper will be divided into two sections A and B. Sec-A consists of 6 questions with alternative choice and 3 should be answered. Each will carry 16 marks and they may be subdivided. Sec -B consists of 6 questions out of which 3 should be answered. Alternative choice will be provided. Among them the last two questions carry 18 marks each and the remaining one 16 marks.

Key Points: Almost all questions are pertaining to the syllabus. Diagrammatic part should be clear and labeled.
