Answer Posted / rahul
The EMF of a transformer at a given flux density increases
with frequency.By operating at higher frequencies,
transformers can be physically more compact because a given
core is able to transfer more power without reaching
saturation and fewer turns are needed to achieve the same
impedance.
So, 50Hz transformer will be the bigger one.
