Critical damping in a second-order series RLC circuit occurs when?

  • Aalpha=0
  • Balpha=omega0
  • Calpha=2omega0
  • Domega0=0
Report an error
Correct Answer: B. alpha=omega0
Explanation: Critical damping occurs at the boundary between oscillatory and nonoscillatory responses, where alpha equals omega0.
