Answer Posted / kishore
X(1 KVA) 50 HZ n Y(1 KVA ) 500 HZ
E = 4.44 f * FLUX * N
that is emf durectly proportional to flux which is f*B*A
B- flux density n A= area of c/s of transformer
as KVA reting of both are same n hence
X (f*B*A) = Y (f*B*A)
as frequency of X is smaller than Y so area of c/s of X
must be larger
hence 50 HZ transformer is largest and so on

Thank,s and Regard,s. Muhammed Ikram.
While converting delta into star or star into delta ,the three values of resistances remains unchanged .Find out the value?Let In star R1=x;r2=x;R3=x On converting into delta,R12=x;R23=x;R31=x Find the value of x
