In a DC load-line analysis of a common-emitter transistor circuit, the Q-point represents?

  • AThe maximum supply voltage only
  • BThe quiescent DC operating point
  • CThe transistor breakdown point only
  • DThe AC frequency response
Report an error
Correct Answer: B. The quiescent DC operating point
Explanation: The Q-point specifies the transistor's steady DC collector current and collector-emitter voltage with no input signal applied.
Reference: Standard analog electronics: transistor biasing
