In a common base circuit of a transistor,the amplification factor is $0.95.$ The base current when the emitter current is $2\,mA,$ is ....$mA$

When the transistor is used as an amplifier,

In a transistor,the value of $\beta$ is $50$. The value of $\alpha$ is ........

In a common emitter transistor amplifier,the resistance of the collector is $3 \ k\Omega$. If the current amplification factor is $100$ and the base resistance is $2 \ k\Omega$,then the power gain of the transistor is:

In a common emitter configuration with suitable bias,it is given that $R_L$ is the load resistance and $R_{BE}$ is the small signal dynamic resistance (input side). Then,the voltage gain,current gain,and power gain are given,respectively,by: [$\beta$ is the current gain,$I_B$,$I_C$,$I_E$ are respectively base,collector,and emitter currents]
