Question

Assertion (A): The deflection in a galvanometer is directly proportional to the current passing through it.
Reason (R): The coil of a galvanometer is suspended in a uniform radial magnetic field.

• 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:

In a moving coil galvanometer, deflection is proportional to the current passing through the coil.

Answer 1

The Correct Option is B

The deflection in a galvanometer is directly proportional to the current passing through it, as per the principle of a moving coil galvanometer. However, the reason provided is not directly related to the deflection, as the deflection is a result of the torque on the coil, which depends on the current. Therefore, both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
