Question

Sensitivity of a potentiometer

Answer 1

A potentiometer is said to be

more sensitive, if it measures a small potential difference more

accurately.

(i) The sensitivity of potentiometer is assessed by its potential

gradient. The sensitivity is inversely proportional to the potential gradient.

(ii) In order to increase the sensitivity of potentiometer

(a) The resistance in primary circuit will have to be decreased.

(b) The length of potentiometer wire will have to be increased so that the length may be measured more

accuracy.

Answer 2

Hey mate

Here is ur answer

The sensitivity of potentiometer means the smallest potential difference that can be measured with the help of it.
It can be increased by decreasing its potential gradient. The same can be achieved by :-
1. By increasing the length of potentiometer wire.
2. By reducing the current in the potentiometer wire circuit with the help of rheostat.
