A transformer is a device as most of the people know it and in a similar way with reference to the law of magnetic stimulation in between coils, electrical transformer is also a piece of equipment or a machine which alter the electrical energy from higher to lower. This electrical transformer facilitate in transmission the AC electric power or broken current from one circuit to a different circuit through electromagnetic stimulation.

Electrical transformers are collection of two or more helixes and ferromagnetic core and it is named as winding. If there will be any electrical modification in the prime winding then in the core it makes an irregular magnetic field, which change by the use of the secondary windings and develops the field. In turn this will stimulates irregular electrical energy in all secondary coils.

Electrical transformers are helping to change the electrical energy in a model train set and they are being used in efficacy poles of most of the electric companies. At the time when electricity shift from an electrical energy plant in the domestic application then it is to be found into a high electrical energy to allow it to pass through lengthy distance. The high electrical energy lines have the ability to pass through hundreds of miles.
