The sensitivity of a potentiometer can be increased by: |
Decreasing the length of potentiometer wire only. Increasing the potential gradient of the potentiometer wire of fixed length. Decreasing the potential gradient of the potentiometer wire of fixed length. Increasing the current in the potentiometer wire circuit. |
Decreasing the potential gradient of the potentiometer wire of fixed length. |
The correct answer is Option (3) → Decreasing the potential gradient of the potentiometer wire of fixed length. To increase sensitivity, we need a smaller potential gradient, which means a smaller voltage drop per unit length. This allows the potentiometer to detect smaller differences in potential, as the voltage difference for each unit length is small. |
