1010603TRANSFORMERSA transformer is a device that uses the action of a magnetic field to change ac electric energy at one voltage level to ac electric energy at another voltage level. It consists of a ferromagnetic core with two or more coils wrapped around it. The common magnetic flux within the core is the only connection between the coils. The source of ac electric power is connected to one of the transformer windings. The second winding supplies power to loads. The winding connected to the power source is called the primary winding or input winding. The winding connected to …
