Potentiometer is defined as an instrument which is used for measuring an electromotive force (emf) by balancing emf against the potential difference that is produced by passing known amount of current.
Sensitivity of Potentiometer Meaning
Sensitivity of potentiometer is defined as the smallest potential difference that is measured by using potentiometer.
Sensitivity of potentiometer can be increased by:
- Increasing the length of the potentiometer wire
- 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.
