As we learnt in
Amplifier -
Transistor is used as an amplifier
- wherein
in such circuit output is amplified as compared to input .
In common emitter amplifier, it will be 180o out of phase with the input voltage waveform. Thus the common emitter amplifier is called an inverting amplifier circuit.
Correct option is 4.
