Sensitivity of potentiometer can be increased by

A

increasing the emf of the cell

B

increasing the length of the potentometer

C

decreasing the length of the potentiometer wire

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
B
Sensitivity of potentiometer means the smallest potential difference it can measure. It can be increased by reducing the potential gradient. The same os possible by increasing the length of the potentiometer.
