1. A transformer is an electrical device t … 1. A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Transformers are used to increase or decrease the alternating voltages in electric power applications.g voltages in electric power applications.
, 2. A transformer is a static machine used … 2. A transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is a very basic definition of transformer. Since there is no rotating or moving part so transformer is a static device. Transformer operates on ac supply. Transformer works on the principle of mutual induction.orks on the principle of mutual induction.
