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:

In a transistor,in common emitter configuration,the ratio of power gain to voltage gain is

In a common emitter amplifier configuration, the current gain is $62$. The collector resistance and input resistance are $5 \text{ k}\Omega$ and $500 \text{ }\Omega$ respectively. If the input voltage is $0.01 \text{ V}$, the output voltage will be (in $V$)

In the common emitter configuration of a transistor,the current gain is more than $1$. Given that $I_{b}$,$I_{e}$,and $I_{c}$ are the base,emitter,and collector currents respectively,which of the following relations is correct?

An $n-p-n$ transistor power amplifier in $C-E$ configuration gives

In the circuit shown,the transistor used has a current gain $\beta = 100$. What should be the base resistor $R_B$ so that $V_{CE} = 5\,V$ and $V_{BE} = 0\,V$?
