The efficiency of power Transformer from primary to secondary
Q.2 The efficiency of power Transformer from primary to secondary
(A) 50%
(B) 60%
(C) 80%
(D) 95%
Exp-: Transformer is a static machine owing to the absence of rotating parts there are no friction or windage losses. Further, the other losses are also relatively low so the efficiency of the transformer is high
