The sensitivity of a potentiometer can be increased by:
- A Decreasing the length of potentiometer wire only.
- B Increasing the potential gradient of the potentiometer wire of fixed length.
- C Decreasing the potential gradient of the potentiometer wire of fixed length.
- D Increasing the current in the potentiometer wire circuit.
Answer & Solution
Correct Answer
(C) Decreasing the potential gradient of the potentiometer wire of fixed length.
Step-by-step Solution
Detailed explanation
Sensitivity is inversely proportional to the potential gradient ( \(k\) ). By decreasing the potential drop per unit length, the potentiometer becomes capable of detecting much smaller changes in potential, making it significantly more precise. C) Decreasing the potential…
