Question

In a potentiometer experiment, the null point is obtained at a particular point for a cell on potentiometer wire x cm long. If the length of the potentiometer wire is increased without changing the cell, the balancing length will (Driving source is not changed)

TestHub · Accepted Answer

On increasing the length of the potentiometer wire, the potential gradient will decrease, hence longer balancing length is required.
