If the length of the potentiometer wire is increased by keeping constant potential difference across the wire, then
- A the null point is obtained at shorter distance.
- B the potential gradient is increased.
- C the null point is obtained at larger distance.
- D there is no change in the null point.
Answer & Solution
Correct Answer
(C) the null point is obtained at larger distance.
Step-by-step Solution
Detailed explanation
Potential gradient \( k = V/L \). If L increases (V constant), k decreases.
