The output impedance of a transistor is____________?
Correct answer: A. high
- A. high
- B. zero
- C. low
- D. very low
Explanation
A transistor's output impedance is generally treated as high, especially in the common-emitter amplifier model, because a change in collector-emitter voltage causes only a small change in collector current. The exact value depends on the transistor and its configuration.
