Expert Answer
In transistor as common base amplifier, the output signal is in phase with input signal; and in transistor as common emitter amplifier the output signal is 180o out of phase with input signal. Transistor as common base amplifier is used when we require better voltage gain, and transistor as common emitter amplifier is used when we require better current gain and power gain.
