When a positive voltage signal is applied to the base of a common emitter `npn` amplifier

Common emitter amplifier

Which one will you prefer, a common base or a common emitter amplifier?

Draw the circuit diagram of a common emitter amplifier using n-p-n transistor. What is the phase difference between the input signal and output voltage? State two reasons why a common emitter amplifier is preferred to a common base amplifier.

Would you prefer to use a transistor as a common base or a common emitter amplifier?

What is the phase difference between input and output signals of common emitter amplifier ?

What kinds of biasing are required to the collector and base of a transistor in a common emitter amplifier?

What kinds of biasing are required to the collector and base of a transistor in a common emitter amplifier?

The current amplification of the common base NPN transistor is 0.96 . What is the current gain if it is used as common emitter amplifier?

An NPN transistor is used in common emitter configuration as an amplifier with 1k Omega load resistance. Signal voltage of 10 mV is applied a across the base-emitter. This produces a 3 mA change in the collector current and 15 mu A change in the base currect of the amplifier. The input resistance and voltage gain are :
