A series RLC natural response is critically damped when the damping factor alpha and undamped natural frequency omega0 satisfy?

  • Aalpha=0
  • Balpha<omega0
  • Calpha=omega0
  • Dalpha>omega0
Report an error
Correct Answer: C. alpha=omega0
Explanation: Critical damping occurs at the boundary between underdamped and overdamped responses, where alpha=omega0.
Reference: Standard network theory: critical damping
