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

In a common base transistor circuit,the current gain is $0.98$. On changing emitter current by $5.00 \,mA$,the change in collector current is ......... $mA$.

The input resistance of a common emitter transistor amplifier,if the output resistance is $500\,k\Omega$,the current gain $\alpha = 0.98$ and power gain is $6.0625 \times 10^6$,is.......$\Omega$.

In the study of a transistor as an amplifier,the ratio of collector current to emitter current is $0.98$. Then,the ratio of collector current to base current will be:

Input signal to a common emitter amplifier having a voltage gain of $1000$ is given by $v_i = (0.004 \, V) \sin(\omega t + \pi/2)$. The corresponding output signal is

The current amplification factor of a transistor is $50$. The input resistance when used in common emitter mode is $1 \text{ k}\Omega$. The peak value of the collector current for an a.c. input voltage of $0.01 \text{ V}$ peak is:
