Define d.c. current gain in common base and common emitter amplifier. Also find a relation between them.

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

With the help of lebelled circuit diagram, discuss the working of transistor as a common emitter amplifier.Find the phase relationship between input and output signals. Also define its voltage gain.

AC current gain for transistor in common emitter amplifier is 20. If input and output resistances are 2 k Omega and 5 K Omega respectively, find: Voltage gain

AC current gain for transistor in common emitter amplifier is 20. If input and output resistances are 2 k Omega and 5 K Omega respectively, find: Power gain

Current gain in common-base configuration is less tham 1, because:
