In potentiometer experiment, null point is obtained at a particular point for a cell on potentiometer wire ' \(x\) ' \(\mathrm{cm}\) long. If length of potentiometer wire is increased by few centimeters without changing the cell, the balancing length will [Driving source is not changed]
- A will not change
- B increase
- C decrease
- D become zero
Answer & Solution
Correct Answer
(B) increase
Step-by-step Solution
Detailed explanation
If the length of potentiometer wire increase, the potential gradient will decrease. Hence to balance the same p.d., the length will increase.
