The length of a potentiometer wire is `l`. A cell of emf `E` is balanced at a length l/3 from the positive end of the wire. If the length of the wire is increased by l/2. At what distance will the same cell give a balance point.

The length of a potentiometer wire is 10 cm. A cell of emf E is balanced at a length 10/3 cm from the positive end of the wire. If the length of the wire is increased by 5 cm, at what distance (in cm) from positive end will the same cell give a balance point?

A steady voltage drop is maintained across a potentiometer wire which is 5m long. A Daniel cell is balanced by a length of 3m of wire. If length of potentiometer wire is increased to 6 m, find new length of wire across which Daniel cell will be balanced.

Figure shows a potentiometer circuit, a cell of emf E_1 is balanced by length l' of the potentiometer wire. If this cell is replaced by another of emf E_2 , it is found that total length of potentiometer wire has to be increased by 50%, in order to have the same balance length (l'). Then E_1//E_2 is______.

A cell of e.m.f. of 1.08 V is balanced by a 216 cm length of a potentiometer. What is the length of the wire that would balance a cell of e.m.f. 1.5 V ?

A constant voltage of 3 V is supplied to a potentiometer wire. A cell of emf 2 V is balanced by a voltage drop across 416 cm of the wire. Find the total length of the potentiometer wire.

In a potentiometer a cell of emf 1.5 V gives a balanced point at 32 cm length of the wire. If the cell is replaced by another cell then the balance point shifts to 65 cm. Then the emf of second cell is

A cell is balanced at 100cm of a potentiometer wire when the total length of the wire is 400cm .If the length of the potentiometer wire is increased by 100cm ,then the new balancing length for the cell will be

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) _________.
