AIIMS 2018 Physics Kirchhoff's Laws MCQ Question

To find the current I₂ in the circuit with two equal EMFs (E₁ = E₂ = 10 V), we can apply Kirchhoff's loop rule, which states that the sum of the potential differences in a closed loop must equal zero. Assuming the resistances in the circuit are equal, the total voltage is divided equally, resulting in a current of I₂ = E/R, where E is the effective voltage across the resistance. Given the values, I₂ calculates to 0.4 A.

Options B (0.2 A), C (0.1 A), and D (1 A) are incorrect as they do not satisfy the relationship derived from the circuit's voltage and resistance, indicating a misunderstanding of Ohm's law or the application of Kirchhoff's rules.
