## What is the basic principle of operation of a transformer?

A transformer consists of two electrically isolated coils and operates on Faraday’s principal of “mutual induction”, in which an EMF is induced in the transformers secondary coil by the magnetic flux generated by the voltages and currents flowing in the primary coil winding.

## Does transformer works on the principle of mutual induction?

A transformer works on the principles of “electromagnetic induction” as a mutual induction. Mutual induction is the process by which a coil of wire magnetically induces a voltage in another closely located coil.

## What is induction and mutual induction?

About Transcript. When changing current in one coil induces an EMF in the other, the phenomenon is called mutual induction. The strength of the EMF induced depends on the mutual inductance of the pair of coils. The S.I.

## What is the advantage of mutual inductance?

A transformer is a device which uses the phenomenon of mutual induction to change the values of alternating voltages and currents. In fact, one of the main advantages of a.c. transmission and distribution is the ease with which an alternating voltage can be increased or decreased by transformers.

## What is mutual induction in simple words?

Mutual induction is defined as the property of the coils that enables it to oppose the changes in the current in another coil. With a change in the current of one coil, the flow changes too thus inducing EMF in the other coil. This phenomenon is known as mutual induction.

## What is the basic difference between distribution transformer and auto transformer?

Key Differences Between Autotransformer and Transformer. An autotransformer has only one winding which acts both as a primary and the secondary whereas the conventional transformer has a two separate windings, i.e., the primary and the secondary winding.

## What is the transformer used for?

A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage.
