In comparing emf's of 2 cells with the helf of potentiometer, at the balance point, the current flowing through the wire is taken from

In comparing emfs of two cells by a potentiometer,balance point is obtained on 5^(th) wire, the current flowing through the wire is taken

In comparing e.m.f. of two cells by a potentiometer balance point is obtained on 5^(th) wire, the current flowing through the wire is taken

How will the sensitivity of a potentiometer change with increase in current flowing through its wire?

The balancing length for a cell in a potentiometer experiment is 45 cm. In the balanced condition, the current through the potentiometer wire is 2 A. If the total length of the potentiometer wire is 1 m and its total resistance is 60Omega , the emf of the cell is (in Volts) _________.
