what is single phase transformer ppt?

A single-phase transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction, operating on a single-phase AC supply. It consists of primary and secondary windings wrapped around a magnetic core. The primary winding receives input voltage, while the secondary winding delivers output voltage, allowing for voltage step-up or step-down. Single-phase transformers are commonly used in residential and light commercial applications for power distribution and voltage regulation.
