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 ....... $mA$.

In a common emitter amplifier,the current gain is $62$. The collector resistance and input resistance are $5\,k\Omega$ and $500\,\Omega$ respectively. If the input voltage is $0.01\,V$,the output voltage is $..........\,V$.

For a transistor amplifier in a common-emitter configuration,given the load resistance $R_L = 1 \ k\Omega$,$h_{fe} = 50$,and $h_{oe} = 25 \ \mu A/V$,calculate the current gain $(A_i)$.

For a transistor,current gain $(\beta) = 50$. To change the collector current by $350 \mu A$,the base current should be changed by:

What is the voltage gain in a common emitter amplifier,where input resistance is $3 \, \Omega$ and load resistance is $24 \, \Omega$,and the current gain $\beta = 0.6$?

In a silicon transistor,a change of $7.89 \, mA$ in the emitter current produces a change of $7.8 \, mA$ in the collector current. What change in the base current is necessary to produce an equivalent change in the collector current (in $mA$)?
