Working Principle of a Transformer
1010603 Working Principle of a TransformerSynopsisA transformer operates on the principle of electromagnetic induction. It has a magnetic core over which two sets of windings, termed as primary and secondary, are suitably placed. When one of the windings is connected to an AC supply, an emf is induced on the other winding which is proportional to the number of turns. This chapter has dealt with the basic formula of an induced emf, linked with voltage per turn, flux density and core area. The alignment chart provides the means of determining rapidly the value of any one factor of the formula when other factors are known.
