What is the power gain in a $CE$ amplifier,where input resistance is $3 \, k\Omega$ and load resistance is $24 \, k\Omega$,given $\beta = 6$?

In a common emitter amplifier,the output resistance is $5000 \Omega$ and the input resistance is $2000 \Omega$. If the peak value of input signal voltage is $100 mV$ and $\beta=50$,then the peak value of output voltage is

The current gain for a common emitter amplifier is $69$. If the emitter current is $7 \ mA$,the base current is......$mA$

If $R_C$ and $R_B$ are respectively the resistances of the collector and base sides of the circuit,and $\beta$ is the current amplification factor,then the voltage gain of a transistor amplifier in common emitter configuration is

An $NPN$ transistor circuit is arranged as shown in the figure. It is:

When an $n-p-n$ junction transistor is used as an amplifier in common emitter mode,
