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 ......... $mA$.

In which of the configurations of a transistor, the power gain is highest?

In an $NPN$ transistor,the collector current is $24 \, mA$. If $80\%$ of electrons reach the collector,its base current in $mA$ is:

In the case of $NPN$ transistors,the collector current is always less than the emitter current because:

For a transistor,$\frac{1}{\alpha_{DC}} - \frac{1}{\beta_{DC}}$ is equal to [where $\alpha_{DC}$ and $\beta_{DC}$ are current amplification factors].

The power gain and voltage gain of a transistor connected in common emitter configuration are $1800$ and $60$ respectively. If the change in the emitter current is $0.62 \text{ mA}$, then the change in the collector current is: (in $\text{ mA}$)
