What is the power gain in a $CE$ amplifier,where the input resistance is $3\,k\Omega$ and the load resistance is $24\,k\Omega$,given $\beta = 20$?

In a common base amplifier,the phase difference between the input signal voltage and the output voltage is

For a transistor,the current ratio $\alpha_{dc} = \frac{69}{70}$,the current gain $\beta_{dc}$ is

For a common emitter transistor,if $\frac{I_{C}}{I_{E}}=0.95$,then the current gain is

In a transistor $(\beta=50)$,the voltage across $5 \, k\Omega$ load resistance in the collector circuit is $5 \, V$. The base current is ......... $mA$.

In an $n-p-n$ common emitter $(CE)$ transistor,the collector current changes from $5\,mA$ to $16\,mA$ for a change in base current from $100\,\mu A$ to $200\,\mu A$,respectively. The current gain of the transistor is:
