In a first-order circuit, after approximately five time constants the transient term has fallen to about?

  • A36.8%
  • B13.5%
  • C5%
  • D0.67%
Report an error
Correct Answer: D. 0.67%
Explanation: The natural term is e^(-t/tau). At t=5tau, e^-5≈0.0067, or about 0.67% of its initial value.
Reference: Standard network theory: settling of first-order response
