transformer is a electromagnetic energy conversion device,
which transforms electrical energy at one level to
electrical energy at a required
(higher/lower/same:stepup/stepdown/isolation)level.
Generally energy conversion is used to enhance any kind of
energy available into a required form of energy we need.
When we consider a transformer from external terminals it is
not a energy conversion device, but it is a energy
conversion device if we see it internally (as it is a
electromagnetic energy conversion device).
Thus by this electromagnetic energy conversion we are able
to get more electrical energy out put when compared to the
magnetic input for the conversion.
If we don't use the transformer we cannot supply consumer
appliances at their required voltage ratings(230V/415V)
