Vedclass · Answer

(C) In a common emitter $(CE)$ transistor amplifier,the input signal is applied between the base and emitter,and the output is taken across the collector and emitter.When the input signal voltage increases,the base current increases,which in turn increases the collector current.Due to the voltage drop across the load resistor in the collector circuit,the output voltage decreases.Conversely,when the input signal voltage decreases,the collector current decreases,leading to an increase in the output voltage.This inverse relationship between the input and output signals results in a phase shift of $\pi$ radians,which is equivalent to $180^o$.

The phase difference between input and output voltages of a $CE$ (common emitter) amplifier circuit is........$^o$.
