how is the sensitivity of a potentiometer increased?

Expert Answer:

Sensitivity of a potentiometer can be increased by decreasing its potential gradient. This can be done
- by increasing the length of potentiometer wire.
- if the potentiometer wire is of fixed length, the potentiometer gradient can be decreased by reducing the current in the potentiometer wire circuit with the help of rheostat and using a single cell.
