Why the size of transformer decreases if we increases the
frequency?
Answer Posted / satish kumar(satty)
EMF of a transformer increases with frequency. As a result the transformer can be physically more compact because a given core is able to transfer more power without reaching saturation and fewer turns are required to achieve the same impedance.
