1KVA transformer of different frequencies of
50hz,100hz,500hz&1000hz. which one of these transformer has
big size? Give reason

Mr. Mohh. Shahid
if v/f=flux
then fr is inversly proportional toflux
then if u increase the fr the flux will decrease
and so the core area also decreases.
all this is for the constant voltage
but for the constant flux the fr is directly proportional
to the voltage
so if the voltage increases the insulation increases and
hence the size of the transformer increases.
then in both the casesthe action is opposite
then how can u say that the size of the transformer
increases.
