What is the voltage gain in a common emitter amplifier,where input resistance is $3 \, \Omega$ and load resistance is $24 \, \Omega$,and the current gain $\beta = 0.6$?

For an $n-p-n$ transistor structure, which of the following statements is $NOT$ true?

For a transistor,the parameter $\beta = 99$. The value of the parameter $\alpha$ is

In a common emitter transistor amplifier,the audio signal voltage across the collector is $3\,V$. The resistance of the collector is $3\,k\Omega$. If the current gain is $100$ and the base resistance is $2\,k\Omega$,what are the voltage and power gain of the amplifier?

The typical output characteristics curve for a transistor working in the common-emitter configuration is shown in the figure. The estimated current gain from the figure is

Given below are two statements:
