NEET Physics Galvanometers Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

Statement I: If the number of turns in the coil of a moving coil galvanometer is doubled then the current sensitivity becomes double.

Statement II: Increasing current sensitivity of a moving coil galvanometer by only increasing the number of turns in the coil will also increase its voltage sensitivity in the same ratio. In the light of the above statement,

choose the correct answer from the options given below:

A

Statement I is false but Statement II is true

B

Both Statement I and Statement II are true

C

Both Statement I and Statement II are false

D

Statement I is true but Statement II is false

Correct Answer

Option B

Detailed Explanation

Both statements are true. Doubling the number of turns doubles the current sensitivity, and since voltage sensitivity is proportional to current sensitivity, it also increases.
