Electrical engineering

Definition: The transformer is an electromagnetic energy conversion device, that transfers electrical energy from one circuit to another circuit without any change in frequency.  During this process of energy transfer, the energy is being converted from electrical to magnetic and back again to electrical energy. The part of the transformer that receives electrical energy from supply mains is known as a primary winding and the part that delivers electrical energy to the load is known as the secondary winding. Single phase transformer The primary and secondary windings of the transformer are not electrically connected but are magnetically coupled. Thus, the electrical energy received by the primary winding is first converted into magnetic energy and then it is converted back into electrical energy in the secondary winding. Working Principle of transformer: The basic working principle of a transformer is "faraday's law of electromagnetic induction" .      According to f...
