Question

Sensitivity of potentiometer

Answer 1

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.

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.
E1E2=l1l21.5E2=60100E2 =52=2.5 V

(ii) The method will not work, if the battery is replaced.
