From the given transfer characteristic of a transistor in $CE$ configuration,the value of power gain of this configuration is $10^x$,for $R_B = 10\,k\Omega$ and $R_C = 1\,k\Omega$. The value of $x$ is $.....$.

For a common-emitter transistor amplifier, the current gain is $60$. If the emitter current is $6.6 \,mA$, then its base current is (in $\,mA$)

$A$ $CE$ amplifier has a voltage gain of $G$. The transistor used has a transconductance of $0.03 \ mho$ and a current gain of $25$. If this transistor is replaced by another transistor with a transconductance of $0.02 \ mho$ and a current gain of $20$,the new voltage gain will be ........

In a transistor, comparing the doping of emitter, base, and collector, the part which is heavily doped and that which is lightly doped are respectively:

In the common emitter mode of a transistor, when the collector-emitter voltage is changed by $0.4 \, V$, the collector current changes by $0.04 \, mA$. The output resistance is

What is the voltage gain of a common-emitter amplifier with an input resistance of $3 \ \Omega$ and a load resistance of $24 \ \Omega$? (Given $\beta = 6$)
