The given transistor amplifier connection is

For a $CE$ amplifier,current gain is $69$. If the emitter current is $7\, mA$,then the base current and collector current will be:

For a common emitter configuration,if $\alpha$ and $\beta$ have their usual meanings,the incorrect relation between $\alpha$ and $\beta$ is

In a transistor configuration,the $\beta$-parameter is defined as:

In a $PNP$ transistor,the base is the $N$-region. Its width relative to the $P$-region is

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