The balancing lengths on a potentiometer wire are `800cm` and `600cm` when two cells of emfs `E_(1)` and `E_(2)` are connected in the secondary circuit first to help each other and next to oppose each other, then `(E_(1))/(E_(2))=`

The balancing lengths of potentiometer wire are l_(1) and l_(2) when two cells of emf E_(1) and E_(2) are connected in the secondary circuit in series first to help each other and next to oppose each other (E_(1))/(E_(2)) is equal to (E_(1)gt E_(2)) .

The balancing lengths of potentiometer wire are l_(1) and l_(2) when two cells of emf E_(1) and E_(2) are connected in the secondary circuit in series first to help eachg other and next to oppose each other (E_(1))/(E_(2)) is equal to (E_(1)gtE_(2))

The balancing lengths of potentiometer wire are 800 cm and 600cm when two cells of emf's E_(1) and E_(2) are connected in the secondary circuit first in series and then terminals of one cell is reversed, E_(1)/E_(2) is equal to

The balancing lengths of potentiometer wire are 800 cm and 600cm when two cells of emf's E_(1) and E_(2) are connected in the secondary circuit first in series and then terminals of one cell is reversed, E_(1)/E_(2) is equal to

The balancing length of a potentiometer wire is 220cm when a cell of emf 1.1v is used in the secondary circuit.If it is replaced by a cell of emf 2.5v the balancing length becomes

The balancing length on a potentiometer wire with a cell of emf 2V and internal resistance 1Omega connected in the secondary circuit with no load is 200cm . If a resistor of 19Omega is connected parallel to the cell, the balancing length

The balancing lengths for the cells of e.m.f. E_(1) and E_(2) are l_(1) and l_(2) respectively. If they are connected separately then

For the working of potentiometer, the emf of cell in the primary circuit (E) compared to the emf of the cell in the secondary circuit (E^(1)) is
