$A$ change of $8.0 \,mA$ in the emitter current brings a change of $7.9 \,mA$ in the collector current. The values of $\alpha$ and $\beta$ are

In a $p-n-p$ transistor,

In a transistor,the base current is $10 \mu A$ and the emitter current is $1 \text{ mA}$. Then,the collector current is: (in $\mu A$)

What is the voltage gain of a common-emitter amplifier with an input resistance of $3 \ \Omega$ and a load resistance of $24 \ \Omega$? (Given $\beta = 6$)

An $npn$ transistor operates as a common emitter amplifier,with a power gain of $60\, dB$. The input circuit resistance is $100\,\Omega$ and the output load resistance is $10\, k\Omega$. The common emitter current gain $\beta$ is:

Given below are two statements:
Statement $I:$ In a typical transistor,all three regions emitter,base and collector have same doping level.
Statement $II:$ In a transistor,collector is the thickest and base is the thinnest segment.
In the light of the above statements,choose the most appropriate answer from the options given below.
