1KVA transformer of different frequencies of
50hz,100hz,500hz&1000hz. which one of these transformer has
big size? Give reason
Answer Posted / mohd shahid
bhai kishore see here we r talking about same KVA rating
not same KV rating.
here you r equting the KV rating(ie by equating the induced
emfs)
there is a diff between kv and kva hence kindly refer again
to your solution which acco. to me is not correct
