What is transformer ? Definition & Working Principle of Transformer
Definition of Transformer Electrical power transformer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between two windings. It transforms power from one circuit to another without changing its frequency but may be in different voltage level. This is a very short and simple definition of transformer , as we will go through this porrical power transformer , we will understand more clearly and deeply " what is transformer ? " and basic theory of transformer . Working Principle of Transformer The working principle of transformer is very simple. It depends upon Faraday's law of electromagnetic induction . Actually, mutual induction between two or more winding is responsible for transformation action in an electrical transformer. Faraday's Laws of Electromagnetic Induction According to these Faraday's laws , "Rat
