JEE Mains · Physics · STD 12 -7. Alternating current
An \(LCR\) circuit as shown in the figure is connected to a voltage source \(V_{ac}\) whose frequency can be varied. The frequency, at which the voltage across the resistor is maximum, is......\(Hz\)
- A \(902\)
- B \(143\)
- C \(23\)
- D \(345\)
Answer & Solution
Correct Answer
(C) \(23\)
Step-by-step Solution
Detailed explanation
Frequency \(\mathrm{f}=\frac{1}{2 \pi \sqrt{\mathrm{LC}}}\) \(=\frac{1}{2 \times 3.4 \sqrt{24 \times 2 \times 10^{-6}}}\) \(=23\, \mathrm{Hz}\)
