In the given circuit current through 2 Ω resistance is:

The correct answer is Option (4) → 1 A

The current through a resistor follows from Ohm's law, \( I = V/R \), where V is the potential difference across the resistor, found by applying Kirchhoff's rules to the circuit.

    \( \displaystyle I = \frac{V_{2\,\Omega}}{2\,\Omega} = 1\,\mathrm{A} \)
