Question

Assertion (A): The mutual inductance between two coils is maximum when the coils are wound on each other.
Reason (R): The flux linkage between two coils is maximum when they are wound on each other.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false and Reason (R) is also false.

Hint:

Mutual inductance is maximum when the coils are wound on each other because the magnetic flux linkage is maximized in this configuration.

Answer 1

The Correct Option is A

Mutual inductance between two coils depends on the extent of magnetic flux linkage between them. When the coils are wound on each other, the magnetic flux linkage is maximum, and hence the mutual inductance is also maximum.
Therefore, both the Assertion (A) and the Reason (R) are true, and Reason (R) correctly explains Assertion (A).
Thus, the correct answer is: \[ \boxed{\text{Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).}} \]
