Question

A series LCR circuit with inductance 10 H, capacitance 10 μF, resistance 50 Ω is connected to an ac source of voltage, V =200 sin(100 t) volt. If the resonant frequency of the LCR circuit is vo and the frequency of the ac source is v, then:

• A. v0 = v = 50 Hz
• B. v0 = v = $\frac{50}{π}$ Hz
• C. v0 = $\frac{50}{π}$ Hz, v = 50 Hz
• D. v0 = 100 Hz, v0 = $\frac{100}{π}$ Hz

Answer 1

Answer: (B)

v0 = v = $\frac{50}{π}$ Hz

Answer 2

The correct answer is (B): v0 = v = $\frac{50}{π}$ Hz
