How is the sensitivity of a potentiometer increased?

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.
