A Wien-bridge oscillator uses R = 10 kOhm and C = 0.01 microfarad in both frequency-selective arms. Its oscillation frequency is closest to?

  • A159 Hz
  • B1.59 kHz
  • C15.9 kHz
  • D159 kHz
Report an error
Correct Answer: B. 1.59 kHz
Explanation: RC = 10000 × 10^-8 = 10^-4 s, so f0 = 1/(2π×10^-4) ≈ 1.59 kHz.
