Transformer basics and working principle,construction,types of transformers,emf equation,voltage transformation ratio is explained in detail. The alternating current supply is given to the first coil and hence it can be called as the primary winding. A transformer is a static electrical device that transfers electrical ene rgy between two or more circuits through electromagnetic induction. When the circuit burden gets too large, the ct secondary voltage becomes. The current transformer consists of only one or very few turns as its primary winding. A transformer basically is very simple static or stationary electromagnetic passive electrical device that works on the principle of faradays law of induction by converting electrical energy from one value to another.
