In a potentiometer arrangement a cell of emf `1.25` V givesn a balance point at 35 cm length of the wire. If the cell is replaced by another cell and the balance point shift to 63 cm, what is the emf of the second cell ?

Text Solution

Verified by Experts

`E propl`
`(E_(1))/(E_(2))=(l_(1))/(l_(2)) " "therefore E_(2)=(l_(2))/(l_(1))xxE_(1)=(63)/(35)xx1.25`
i.e.,`E_(2)`=2.25V
