Transformer - Definition, Types, Working Principle, Equations & Examples

Transformer is a device that transfer electrical energy from one alternating-current circuit to another circuit or multiple circuits. Transformer works on the principle of electromagnetic induction. Transformers either increase AC voltage (Step-up transformer) or decreases AC voltage (Step-down transformer).
