Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The mutual inductance of coil 1 with respect to coil 2 is the same as mutual inductance of coil 2 with respect to coil 1.
Reason (R) : Mutual inductance between coils is independent of current passing through the coil In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
B. Both (A) and (R) are true and (R) is NOT the correct explanation of (A).
Step-by-step solution
- Assertion (A) states that the mutual inductance of coil 1 with respect to coil 2 is the same as the mutual inductance of coil 2 with respect to coil 1 (). This is a fundamental property of mutual inductance, often referred to as the reciprocity theorem for mutual inductance. So, Assertion (A) is true.
- Reason (R) states that mutual inductance between coils is independent of the current passing through the coil. Mutual inductance (M) is a geometric and physical property of the coil arrangement (number of turns, area, separation, core material, etc.). It describes how effectively the magnetic flux produced by one coil links with another. It does not depend on the actual current flowing in the coils. So, Reason (R) is true.
However, Reason (R) is NOT the correct explanation for Assertion (A).
