Current Electricity question

2021 · 22 Jul · Shift 2 · Q71

JEE MainPhysicsCurrent ElectricityNumerical+4 / −1
In an electric circuit, a cell of certain emf provides a potential difference of 1.25 V across a load resistance of 5 Ω\OmegaΩ. However, it provides a potential difference of 1 V across a load resistance of 2 Ω\OmegaΩ. The emf of the cell is given by x10V{x \over {10}}V10x​V. Then the value of x is ‾\underline{\hspace{2cm}}​.
