Why the size of transformer decreases if we increases the
frequency?
Answer Posted / chandan kumar
E=4.44bafn V
so if we increase the supply frequency the induced emf
increases
and the active power of transformer is given by P=VI,
SO POWER DEVELOPED IS INCREASES of the same t/f
if we increase the frequency
therefor the size is decreases
