Answer & Solution

Correct Answer

(B) \( \frac{3\sqrt{2}}{2} \text{ A} \)

Step-by-step Solution

Detailed explanation

Inductive Reactance \(\left(X_L\right)\) : \(X_L=\omega L=500 \times\left(10 \times 10^{-3}\right)=5 \Omega\) Capacitive Reactance \(\left(X_C\right)\) : \(X_C=\frac{1}{\omega C}=\frac{1}{500 \times 400 \times 10^{-6}}=\frac{1}{0.2}=5 \Omega\) Since \(X_L=5 \Omega\) and…
