Physics Question 48 – JEE-MAIN 2025

Two cells of emfs $1\text{ V}$ and $2\text{ V}$ and internal resistances $2\mathrm{\Omega }$ and $1\mathrm{\Omega }$, respectively, are connected in series with an external resistance of $6\mathrm{\Omega }$. The total current in the circuit is $I_1$. Now the same two cells in parallel configuration are connected to same external resistance. In this case, the total current drawn is $I_2$. The value of $\left(\frac{I_1}{I_2}\right)$ is $\frac{x}{3}$. The value of $x$ is _______.
