Question

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, the number of turns in primary and secondary are made 10 and 5 respectively. Mutual inductance of the transformer will be (A) 25H (B) 12.5H (C) 50H (D) 6.25H

As M propto N1N2, therefore, M remains the same.

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, the number of turns in primary and secondary are made $10$ and $5$ respectively. Mutual inductance of the transformer will be

$25 H$

$12.5 H$

$50 H$

$6.25 H$

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