Q. The number of turns of primary and secondary coils of a transformer is 5 and 10 respectively and mutual inductance of the transformer is 25 H. Now, number of turns in primary and secondary are made 10 and 5 respectively. Mutual inductance of transformer will be

A) 25 H
B) 12.5 H
C) 50 H
D) 6.25 H
Explanation

(a) As $M\ \propto N_{1}N_{2},\ $therefore, M remains the same.
