Question

to increase sensitivity of a potentiometer its?

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

Answer:

sensitivity proportional to the length

and potential gradient depends upon the length of wire where sensitivity is inversely proportional 1/potential gradient
