In a potentiometer experiment, two cells connected in series get balanced at 9 m length of the wire. Now, if the connections of terminals of cell of lower emf are reversed, then the balancing length is obtained at 3 m. The ratio of emf's of two cells will be

Two cells when connected in series are balanced on 8 m on a potentiometer. If cells are connected with polarities of one the cellis reversed, they balance on 2 m . The ratio of e.m.f.'s of the two cellsis

Two cells of E.M.F. E_(1) and E_(2)(E_(2)gtE_(1)) are connected in series in the secondary circuit of a potentiometer experiment for determination of E.M.F. The balancing length is found to be 825 cm. Now when the terminals to cell E_(1) are reversed, then the balancing length is found to be 225 cm. The ratio of E_(1) and E_(2) is

Two cells when connected in series are balanced on 6 m on a potentiometer. If the polarity one of these cell is reversed, they balance on 2m. The ratio of e.m.f of the two cells.

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 , the balancing length for a cell was found to the 1.20 M . Now , a resistance of 10 Omega is connected across the terminals of this cell and the balancing length becomes 80 cm . The internal resistance of this cell is .

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 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
