Reported Question / Answer
answer should be 2
100KVA, 25 Hz is the correct answer because for the same KVA rating, as the frequency increases the size of transformer decreases. therefore the KVA rating i.e 100 is constant but the frequency is changing so at the frequency 25Hz we will have the transformer of smallest size while on the frequency of 100Hz at the same KVA rating we will have largest transformer size
