Question

what is transformer?also explain power loses in transformer.

Answer 1

TRANSFORMER
an apparatus for reducing or increasing the voltage of an alternating current.
2)a person or thing that transforms something.
Hysteresis Loss
The core of the transformer is subjected to an alternating magnetising force, and for each cycle of emf, a hysteresis loop is traced out. Power is dissipated in the form of heat known as hysteresis loss

Answer 2

Explanation:

Losses in transformer

In any electrical machine, 'loss' can be defined as the difference between input power and output power. An electrical transformer is an static device, hence mechanical losses (like windage or friction losses) are absent in it.
