How Power Transformers Work
The working of power transformers works on the basic principle of electromagnetic induction They are composed of primary and secondary windings that are arranged about a core When an alternating current passes through the primary winding a magnetic field is established which in turn induces a current in the secondary winding This phenomenon makes it possible to transfer electrical energy from one circuit to another through a change in voltage This fluidity or transfer of energy concepts is the factor that determines the operation of power transformers and how effective the electrical devices will be in relation to the amount of voltage supplied
