transformer transfer electrical energy from circuit to
another without changing its supply frequency.so it is rated
in KVA and not in Kw.

Answer / sirisha

transformer is a static device which is used to transform
the energy from one circuit to another circite witout
change in freequency.there is no moving parts so lossess
are less when compared to any machine.transformer rating
measured in kva only
if u ak any qn i will answer u

Mutual induction

Answer / saravanan.p

The fundamentals of transformer is the transfer the energy
from one circuit to other circuit due to magnetic induction
between them without changing the frequency. Here no
movable parts. So losses are highly reduced.

Magnetic Induction (M) = L.dt/dI.
