The phase difference between the input and output voltages of a transistor connected in common emitter arrangement is___________?
Correct answer: B. 180o
- A. 0o
- B. 180o
- C. 90o
- D. 270o
Explanation
A common-emitter amplifier reverses the output voltage relative to the input, giving a phase difference of 180°. This inversion is the characteristic phase property of the common-emitter configuration.
