In a potentiometer experiment, the null point is obtained at a particular point for a cell on potentiometer wire long. If the length of the potentiometer wire is increased without changing the cell, the balancing length will (Driving source is not changed)
- A increase
- B decrease
- C not change
- D becomes zero
Answer & Solution
Correct Answer
(A) increase
Step-by-step Solution
Detailed explanation
On increasing the length of the potentiometer wire, the potential gradient will decrease, hence longer balancing length is required.
