MCQ
Sensitivity of potentiometer can be increased by
- AIncreasing the $e.m.f.$ of the cell
- ✓Increasing the length of the potentiometer wire
- CDecreasing the length of the potentiometer wire
- DNone of the above
✓
Answer
Correct option: B.
Increasing the length of the potentiometer wire
b
The sensitivity of potentiometer can be increased by decreasing the potential gradient i.e., by increasing the length of potentiometer wire. (Sensitivity $\propto \frac{1}{P . G .}$ and Length)
