In electronic, measurement and control circuits, transformer size may be so small that it weight only a few tens of grams where as in high voltage power circuits, it may weight hundred of tones. As such transformers are built in an amazing strength of sizes. A transformer is most widely used device in both low and high current circuit. INTRODUCTION The transformer is a device used for converting a low alternating voltage to a high alternating voltage or vice-versa.Ī 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 neighboring coil.Ī transformer is an electrical device which is used for changing the A.C.
