In a potentiometer experiment, the balancing length is found to be 1.8 m for a cell of e.m.f. 1.5 V. What is the balancing length for a cell of e.m.f. 1 V ?

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).

In a potentiometer the balancing length of the wire is found to be 2.5 m for a cell of e.m.f. 1.5V . Find the balancing length of the wire fore another cell of e.m.f. 1.2 V on the same potentiometer.

In potentiometer experiment, if l_(1) is the balancing length for e.m.f. of the cell of internal resistance r and l_(2) is the balancing length for its terminal potential difference when shunted with resistance R then :

In a potentiometer experiment two cells of e.m.f. E and E are used in series and in conjunction and the balancing length is found to be 58 cm of the wire. If the olarity of E is reversed, then the balancing length becomes 29 cm . The ratio (E_(1))/(E_(2)) of the e.m.f. of the two cells is

In a potentiometer experiment two cells of e.m.f. E1 and E2 are used in series and in conjunction and the balancing length is found to be 58 cm of the wire. If the polarity of E2 is reversed, then the balancing length becomes 29 cm . The ratio (E_(1))/(E_(2)) of the e.m.f. of the two cells is

In a potentiometer experiment two cells of e.m.f. E1 and E2 are used in series and in conjunction and the balancing length is found to be 58 cm of the wire. If the polarity of E2 is reversed, then the balancing length becomes 29 cm . The ratio (E_(1))/(E_(2)) of the e.m.f. of the two cells is

In a potentiometer experiment the balancing length is 8 m, when the two cells E_(1) and E_(2) are joined in series. When the two cells are connected in opposition the balancing length is 4m. The ratio of the e.m.f. of two cells (E_(1)//C_(2)) is

In potentiometer experiment, a cell of emf 1.25 V gives balancing length of 30 cm. If the cell is replaced by another cell, then balancing length is found to be 40 cm. What is the emf of second cell ?
