Question:
Sensitivity of moving coil galvanometer can be increased by :
Sensitivity of moving coil galvanometer can be increased by :
Show Hint
Increasing the area of the coil increases the sensitivity of the moving coil galvanometer.
Updated On: Oct 8, 2025
- decreasing area of the coil
- decreasing number of turns in the coil
- increasing area of the coil
- decreasing value of magnetic field
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Galvanometer Sensitivity.
The sensitivity of a galvanometer is directly proportional to the number of turns of the coil and the area of the coil. Increasing the area of the coil or the number of turns increases the sensitivity.
Step 2: Conclusion.
Thus, the sensitivity of the moving coil galvanometer can be increased by increasing the area of the coil. Therefore, the correct answer is option .
