Transformer
Introduction A transformer is a static electrical machine which transfers AC electrical power from one circuit to the other circuit at the constant frequency, but the voltage level can be altered that means voltage can be increased or decreased according to the requirement. Working Principle The working principle of transformer is very simple, Mutual inductions between two or more windings is responsible for transformation action in an electrical transformer. Basic Theory of Transformer Say you have one winding which is supplied by an alternating electrical source. The alternating current through the winding produces a continually changing flux or alternating flux that surrounds the winding. If any other winding is brought nearer to the previous one, obviously some portion of...
