Q. Sensitivity of potentiometer can be increased by
A) Increasing the e.m.f. of the cell
B) Increasing the length of the potentiometer wire
C) Decreasing the length of the potentiometer wire
D) None of the above
Explanation
(b) The sensitivity of potentiometer can be increased by decreasing the potential gradient $i.e.$ by increasing the length of potentiometer wire
[Sensitivity $\propto \frac{1}{P.G.} \propto$ Length]
