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

A potentiometer wire of length 10 m is connected in series with a battery the emf of a cell balances against 250 cm length of wire if length of potentiometer wire is increased by 1 m then new balancing length of wire will be

In potentiometer experiment, null point isobtained at a particular point for a cell on potentiometer wire x cm long. If the lengthof the potentiometer wire is increasedwithout changing the cell, the balancing length will (Driving source is not changed)

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.

A cell of emf E and internal resistance r connected in the secondary gets balanced against length l of potentiometer wire. If a resistance R is connected in parallel with the cell, 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) _________.
