Answer & Solution

Correct Answer

(A)  \(1 \mathrm{~A}\)

Step-by-step Solution

Detailed explanation

\(\mathrm{R}_{\mathrm{eq}}=2 \Omega+2 \Omega+1 \Omega=5 \Omega\) \(\mathrm{i}=\frac{\mathrm{V}}{\mathrm{R}_{\mathrm{eq}}}=\frac{10}{5}=2 \mathrm{~A}\) Current in resistance \(\mathrm{R}_3=2 \times\left(\frac{4}{4+4}\right)\) \( =2 \times \frac{4}{8} \) \( =1 \mathrm{~A}\)
