When a transistor is used as a $CB$ transistor amplifier,the current gain is $0.8$. If the change in base current is $6 \ mA$,then the change in collector current is ....... $mA$.

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 $.....$.

To use a transistor as an amplifier,which of the following conditions must be satisfied?

An $npn$ transistor operates as a common emitter amplifier with a power gain of $10^{6}$. The input circuit resistance is $100\, \Omega$ and the output load resistance is $10\, k\Omega$. The common emitter current gain $\beta$ will be (Round off to the nearest integer).

For a $CE$ amplifier,the current gain is $60$. If the load resistance is $5 \times 10^3 \ \Omega$ and the input resistance is $5 \times 10^2 \ \Omega$,then the voltage gain is .......

$A$ transistor connected in common emitter mode has a load resistance of $5 \, k\Omega$. If the input peak voltage is $5 \, mV$ and the current gain $(\beta)$ is $50$, find the voltage gain.
