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!

Answer / k.prakashchandra

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

Answer / javad

No.there is an expansion and contraction in each cycle.cld
magnetostriction,hence producing humming sound. if we
increas the frequency the rate of exp n con increase.

Answer / raj

yes it will increase
