A 10 wire potentiometer has first five wires of cross sectional radius r and next five wires of radius 2r . The wires are uniform and made of same material. An ideal cell of emf 2 V is connected across the potentiometer wire. What length of the potentiometer wire will balance the emf of– (a) a Daniell cell (emf = 1.0 V) (b) a Lechlanche cell (emf = 1.5 V) (c) a cell of emf 1.8 V ? Length of each wire is 100 cm.

The emf of a cell is Ev , and its its internal resistance is 1Omega . A resistance of 4Omega is joined to battery in parallel. This is connected in secondary circuit of potentiometer. The balancing length is 160 cm. If 1 V cell balances for 100 cm of potentiometer wire, the emf of cell E is

In a potentiometer experiment, balancing length is found to be 120cm for a cell E_(1) of e.m.f. 2V. What will be the balancing length for another cell E_(2) of e.m.f. 1.5V ? (No other changes are made in the experiment).

Resistance of potentiometer wire is 0.1Omega//cm . A cell of emf 1.5V is balanced at 300cm on this potentiometer wire. Calculate the current and balancing length for another cell of emf 1.4V on the same potentiometer wire.

The emf of cell is balanced by balancing length 450 cm . When the resistance of 10 Omega is connected across the cell, balancing length changes by 100 cm. The internal resistance of a cell is
