Answer Posted / shubham joshi
During the half of the input signal the potential of base with respect of emitter is less negative as a result current Ic decreases which results increasing in collector voltage Vc .Icr decreses hence mathematically Ve increases bcoz collector is joined at low potential during the negative half of a input signal . the low potential of base decrease hence potential difference Vbe increase .in this way opposite signals are obtained in diff. half cycle of input signal and having a phase difference of 180 between input and output centre.
