COMEDK · Physics · 23. Alternating Current
In the series \(L-C-R\) circuit shown, the impedance is
- A \(200 \Omega\)
- B \(100 \Omega\)
- C \(300 \Omega\)
- D \(500 \Omega\)
Answer & Solution
Correct Answer
(D) \(500 \Omega\)
Step-by-step Solution
Detailed explanation
Here, \(L=1 \mathrm{H}, C=20 \mu \mathrm{F}, R=300 \Omega\) \(\begin{aligned} & X_L=2 \pi f L=2 \pi\left(\frac{50}{\pi}\right) \times 1=100 \Omega \\ & X_C=\frac{1}{2 \pi f C}=\frac{1}{2 \pi\left(\frac{50}{\pi}\right) 20 \times 10^{-6}}=500 \Omega \end{aligned}\) Impedance,…
