NEET Physics Galvanometers Assertion Reason Question
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:
Statement I is false but Statement II is true
Both Statement I and Statement II are true
Both Statement I and Statement II are false
Statement I is true but Statement II is false
Correct Answer
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.
