In a potentiometer arrangement, a cell of emf 1.5 V gives a balance point at 27 cm length of wire. If the cell is replaced by another cell and balance point shifts to 54 cm, the emf of the second cell is :

A

3V

B

1.5V

C

0.75V

D

2.25V

To solve the problem, we will use the principle of a potentiometer which states that the EMF (electromotive force) of two cells can be compared using the lengths of wire where they balance. The relationship is given by the formula: \[ \frac{E_1}{E_2} = \frac{L_1}{L_2} \] Where: - \(E_1\) is the EMF of the first cell, ...
