Transformer: An integral part of electrical and electronic industries.
A transformer is an electrical machine that does not have any moving or rotating components. A transformer is probably the most widely used electrical appliance in electrical equipment. It transfers electrical energy from one circuit to another circuit using electrical induction through interconnected conductors. The transformer works only with alternating current or potential difference, not with direct. Transformers can be single-phase, three-phase, or multi-phase. It is the most efficient machine among all electrical machines. In the modern era, transformer has become an integral part of electrical and electronic industries.
A transformer may have one, two, or more windings. The number of turns of primary and secondary windings of a two-winding transformer and their potential difference has relationship with each other.
