A) \[{{135}^{o}}\]
B) \[{{180}^{o}}\]
C) \[{{45}^{o}}\]
D) \[{{90}^{o}}\]
Correct Answer: B
Solution :
In common emitter amplifier circuit input and output voltage are out of phase. When input voltage is increased then \[{{i}_{b}}\] is increased,\[{{i}_{c}}\] also increases so voltage drop across\[{{R}_{c}}\]is increased. However increase in voltage across \[{{R}_{C}}\]is in opposite sense.You need to login to perform this action.
