It doesn't 'do' anything! It just tells you what factors affect the emf.

What is construction and working of single phase transformer?

The single phase transformer works on the principle of mutual induction. Explanation: When an alternating voltage V1 is applied to a primary winding, an an alternating current I1 flows in it producing an alternating flux in the core. As per Faraday's law of electromagnetic induction, an emf e1 is induced in the primary winding. Where N1 is the number of the turns in the primary winding's induced emf in the primary winding is nearly equal and opposite to the applied voltage V1

How emf induce while apply in primary side of the transformer?

when an alternating current apply on primary side of transformer then magnetic flux produced in the iron core of transformer.Then flux link with secondary winding of transformer so that an emf produced in a transformer.

The usual way is with a synchronous generator connected to the distribution system.


What is the main cause for the coefficient of coupling of a transformer being less than unity?

initially the induced emf i.e.,self inductance is high than mutually induced emf in the other .....so coefficient of coupling is high


If the primary winding of a double wound transformer is supplied with the direct current its iron core will become magnetized but there will be no emf induced in the secondary winding?

BECAUSE YOU NEED AC EFFECT TO INDUCE EMF IN TO SECONDARY WINDING.OR DC PULSING.


Why Back EMF occur in only dc motor?

It doesn't. It exists in all electrical machines, d.c. or a.c., motor, generator, or transformer.
