Question

To increase sensitivity of a potentiometer, its

A) Area should be increased

B) Current should be decreased

C) Current should be increased

D) Length should be increased

Answer 1

The correct option is B) Current should be decreased. Sensitivity of potentiometer can be increased by. Sensitivity of potentiometer can be increased by increasing the length of the potentiometer wire and by reducing the current in the circuit by using a rheostat.  Both the methods help in decreasing the potential gradient, and thereby increasing the resistivity.
