Two cells of emfs 1 V and 2 V and internal resistances 2 Ω and 1 Ω, respectively, are connected in series with an external resistance of 6 Ω. The total current in the circuit is I₁. Now the same two cells in parallel configuration are connected to same external resistance. In this case, the total current drawn is I₂. The value of (I₁/I₂) is x/3. The value of x is _ _ _.
