# the dc collector current ic of the cb amplifier is equal to

• As the voltage gain of the common collector amplifier is considered to be unity (1), the amplifiers power gain must be equal to its current gain, as P = V*I. Since the common collector current gain is defined as the ratio of the emitter current to the base current, γ = I E /I B = β + 1 , it therefore follows that the amplifiers current gain must be approximately equal to Beta …
