What is the Working Principle of a Transformer?
By BYJU'S Exam Prep
Updated on: September 25th, 2023
The working principle of a transformer is based on the law of mutual induction of Faraday. It states that when a magnetic flux which is linked to a circuit changes, it will induce an electromotive force current.
Transformer
- It is a device that either raises or lowers the voltage as it distributes electrical energy from one alternating current circuit to one or more circuits.
- To run low voltage devices, transformers are employed to lower the voltage of traditional power circuits.
- Additionally, it is employed to increase the voltage coming from electric generators so that long-distance transmission of electric power is possible.

Working principle
- The mutual induction law of Faraday is the basis of the transformer.
- According to Faraday’s law of electromagnetic induction, an electromotive force current will induce itself into a circuit whenever there is a change in the magnetic flux that is connected to it.
- Only alternating current can be used because mutual induction between the two windings requires an alternating flux.
- The laminated silicon steel core is covered by two distinct windings that make up the transformer.
- The primary winding is the one to which the AC supply is linked, and the secondary winding is the one to which the load is connected.
- This induced emf is flowing in the opposite direction to the applied voltage.
- An alternating flux forms in the transformer’s core and links with the secondary winding as soon as a specific voltage of AC power is applied to the primary winding. This causes an induced emf in the secondary winding that is known as a mutually induced emf.
Summary:-
What is the Working Principle of a Transformer?
A transformer’s operation is governed by Faraday’s law of mutual induction. It claims that an electromotive force current will be induced when a magnetic flux connected to a circuit changes.
