Question

In potentiometer experiment, null point is obtained at a particular point for a cell on potentiometer wire ' x ' 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], will not change, increase, decrease, become zero

MARKS App · Accepted Answer

If the length of potentiometer wire increase, the potential gradient will decrease. Hence to balance the same p.d., the length will increase.
