JEE Mains · Physics · STD 12 -7. Alternating current
In an ac circuit, an inductor, a capacitor and a resistor are connected in series with \({X}_{{L}}={R}={X}_{{C}}\). Impedance of this circuit is:
- A \(2 {R}^{2}\)
- B Zero
- C \({R}\)
- D \({R} \sqrt{2}\)
Answer & Solution
Correct Answer
(C) \({R}\)
Step-by-step Solution
Detailed explanation
\(Z=\sqrt{\left(X_{L}-X_{C}\right)^{2}+R^{2}}=R: \because X_{L}=X_{C}\)
