For a stable first-order circuit excited by a constant DC source, the natural-response component as t approaches infinity?

  • AGrows without bound
  • BApproaches zero
  • CBecomes equal to the source voltage in every circuit
  • DOscillates indefinitely

Correct Answer: B. Approaches zero
Explanation: A stable first-order natural term has the form Ke^(-t/tau), which decays to zero as time increases.
Reference: Standard network theory: natural response decay
