Answer / amir rashid chishti
If we increase the frequency then transformer size will
reduce so it will not increase. In electronics circuits we
often see very small transformers due to high frequency
whereas in power systems we have large size transformers
due to low frequency.
Hope answered the question!

It will reduce as less flux is required to build the same back emf which is equal to 4.44 x flux x frequency x turns
