If voltage feedback (negative) is applied to an amplifier, its output impedance ______________?
Correct answer: C. Is decreased
- A. Remains the same
- B. Is increased
- C. Is decreased
- D. None of the above
Explanation
Voltage-series negative feedback lowers output impedance because the feedback amplifier opposes changes in output voltage. This improves the amplifier's ability to drive a load.
