For a transistor,the parameter $\beta = 99$. The value of the parameter $\alpha$ is

$A$ transistor has a current amplification factor of $60$. In a $CE$ amplifier, input resistance is $1 \, k\Omega$ and output voltage is $0.01 \, V$. The transconductance is (in $SI$ units)

$A$ 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.

Consider an amplifier circuit in which a transistor is used in common-emitter mode. The load resistance is $3 k \Omega$. When a signal of $30 mV$ is added to the base-emitter voltage, the base current changes by $30 \mu A$ and the collector current changes by $3 mA$. The power gain in this circuit will be:

$A$ transistor having $\alpha = 0.99$ is used in a common base amplifier. If the load resistance is $4.5 \, k\Omega$ and the dynamic resistance of the emitter junction is $50 \, \Omega$,the voltage gain of the amplifier will be:

In a junction transistor, the collector current changes by $6.8 \,mA$, if the emitter current is changed by $7 \,mA$. For such a transistor, the current amplification factor is
