The phase difference between the output and input voltages of a CE amplifier is _____________?
Correct answer: A. 180o
- A. 180o
- B. 0o
- C. 90o
- D. 270o
Explanation
In a CE amplifier, an increase in input voltage increases collector current and the voltage drop across RC, causing collector output voltage to decrease. This produces a 180° phase difference between output and input.
