Question # 1
How the power is lost due to eddy current in a transformer and how this loss can be minimized?
- Ans 1: The induced currents that are set up in the core of transformer in the direction perpendicular to the flux are known as eddy currents,It results in power dissipation and heating of the coral material.The insulation between lamination sheets should be perfect so as to stop the flow of eddy currents.

Question # 1
Can a transformer be used with D.C? Explain
- Ans 1: No As transformer works on the principle of electromagnetic induction,which is produced by A.C and not by D.C,To induced a voltage in the secondary coil it is necessary to have magnetic flux change.

Question # 1
In a transformer there is no transfer of charge from the primary to the secondary.How is then the power transferred?
- Ans 1: The power will be transferred because the two coils of transformer are magnetically linked i.e, the change of flux through one coil is linked with the other coil.
