investigatory project in physics for class 11 cbse pdf

is supplied to the primary coil p1p2, an alternating current starts falling in it. Theory And Working: When an altering e.m.f. Further, the energy loses due to magnetic the iron core is also negligible. For an ideal transformer, we assume that the resistance of the primary & secondary winding is negligible.

thus there can be no current through the sec. Note that the both the coils are insulated from the core, the source of alternating e.m.f is connected to p1p2, the primary coil and a load resistance R is connected to s1 s2, the secondary coil through an open switch S. Two coils p1 & p2 and s1 & s2 are wound on the same core but are well insulated with each other. Construction: A transformer consists of a rectangular shaft iron core made of laminated sheets, well insulated from one another. number of turns in secondary coil of self-designed transformer Principle: A Transformer based on the Principle of mutual induction according to this principle, the amount of magnetic flux linked with a coil changing, an e.m.f is induced in the neighbouring coil. 1 Aim of the project: To investigate the relation between the ratio of: - 1. I am also thankful for the help rendered by the Lab Assistant who made available the various apparatus needed for the experiment. It is he who has been motivated, guided and encouraged me at different stages to make this Project. Priyanka Singh under whose guidance I am able to undertake this Project. Date: Internal Examiner (Subject Teacher) Signature Principals Signature External Examiner Signature _ 2 Acknowledgement It is my foremost duty to express my deep regards and gratitude to my Physics Teacher Ms. Kendriya Vidyalaya NHPC, Singtam has satisfactorily completed the Project on Physics on the topic: AC Transformer, as prescribed by the AISSCE course in the academic year I have examined the Project and hereby accord my approval of it’s as a study carried out and presented in the manner required for its acceptance.
