why transformer has more efficiency compare to rotating
machine?
Answer Posted / harjeet singh
transformers where the primary and secondary windings were
of identical inductance, giving approximately equal voltage
and current levels in both circuits. Equality of voltage
and current between the primary and secondary sides of a
transformer, however, is not the norm for all transformers.
If the inductances of the two windings are not equal &
their is no any firction losses in transformerso trasformer
has mor efficiency as compare to rotating machine.
