MCQ
Best method to increase the sensitivity of the moving coil galvanometer is to decrease:
- ARadius of the coil
- BNumber of turns of the coil
- CExternal magnetic field
- ✓Couple per unit twist
✓
Answer
Correct option: D.
Couple per unit twist
Sensitivity of a galvanometer increases when radius of the coil, number of turns of the coil and external magnetic field increases whereas couple per unit twist decreases.
