SUMMARY
In transformer operation, when an alternating voltage is applied across the primary coil, an electromotive force (emf) is induced in the secondary coil, resulting in an alternating current. This principle is fundamental to the functioning of transformers, which rely on electromagnetic induction to transfer energy between coils. The relationship between the primary and secondary voltages and currents can be described by the transformer equations, specifically the turns ratio and Faraday's law of electromagnetic induction.
