| Assertion (A): In moving coil galvanometer, the coil is wound on a metallic frame. |
| Reason (R): The metallic frame helps in making steady deflection without oscillation. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: A
Solution :
Option [a] is correct. Explanation: Coil of a moving coil galvanometer is wound on a metal frame. So, the assertion is true. It is done to avoid any oscillation and fluctuating reading. The metal frame provides damping to reduce the oscillation so that the reading becomes steady. So the reason is also true and properly explains the assertion.
