Question
In a common emitter amplifier circuit using an transistor, the phase difference between the input and the output voltages will be:
Choose an option
Show full solutionCorrect option: A
Correct answer
A
Step-by-step explanation
In a common emitter amplifier circuit, the input voltage must be forward biased and output voltage must be reversed biased.
So the input voltage must be out of phase of output voltage.
Therefore, the phase difference between the input and output voltage is .Practice this on the real CBT interface
