MCQ
In a common emitter amplifier circuit using an $n-p-n$ transistor, the phase difference between the input and the output voltages will be.....$^o$
- A$45$
- B$90$
- C$135$
- ✓$180$
✓
Answer
Correct option: D.
$180$
d
In common emitter configuration for $n-p-n$ transistor input and output signals are $180^o$ out of phase i.e., phase difference between output and input voltage is $180^o$ .
