How will u increase the sensitivity of potentiometer?
Answers
hey mate ,
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.
Hope you find it helpful!!!

Sensitivity of a Potentiometer:
It means the smallest potential difference which can be measured by the Potentiometer.
How to increase its sensitivity:
To make it sensitive, the potential gradient must be low. So by increasing the length of the wire, the potential gradient reduces as it is inversely proportional to its length and the potentiometer becomes more sensitive. Also, you can increase its sensitivity by reducing the current in the circuit by using a rheostat. It also helps in decreasing the gradient.
