Question

What do you understand by sensitivity of potentiometer ? How can we increase it.

Answer 1

A potentiometer is sensitive if-

1. it is capable of measuring very small
potential differences.
2. it shows a significant change in balancing length for a small change in the potential
difference being measured.

The sensitivity of a potentiometer can be increased by reducing the potential gradient and it can be done in the following ways-

1. increasing the length of potentiometer wire
2. reducing the current using a rheostat.
