Answer & Solution

Correct Answer

(B) \(5\)

Step-by-step Solution

Detailed explanation

\( \mathrm{i}_{3}+\mathrm{i}_{2} =\mathrm{i}_{1} \) \( \frac{20-\mathrm{v}}{2} +\frac{10-\mathrm{v}}{4}=\frac{\mathrm{v}}{2} \) \( \mathrm{v}=10 \,\mathrm{V} \) \(\Rightarrow \quad \mathrm{i}_{1} =\frac{10}{2} \) \(=5 \,\mathrm{amp} \)
