In the given transistor circuit,the base current is $35 \ \mu A$. If the value of $V_{BE}$ is negligible,what is the value of $R_b$ in $k\Omega$?

For a common base transistor,the current gain is $\alpha = 0.98$. To produce a change of $2 \ mA$ in the emitter current,the change in the base current must be ......... $mA$.

The current gain of a transistor in common emitter configuration is $80$. The resistances in collector and base sides of the circuit are $5 \text{ k}\Omega$ and $1 \text{ k}\Omega$ respectively. If the input voltage is $2 \text{ mV}$, the output voltage is: (in $\text{ V}$)

For a transistor in $CE$ mode to be used as an amplifier,it must be operated in:

In an $n-p-n$ transistor circuit,the collector current is $10 \, mA$. If $90 \%$ of the electrons reach the collector,then the emitter current will be:

The load resistance and the base-emitter voltage of a transistor in $CE$ configuration are $5 \ k\Omega$ and $0.02 \ V$ respectively. If the collector current is $2 \ mA$,then its voltage gain is
