For a transistor,current gain $(\beta) = 50$. To change the collector current by $350 \mu A$,the base current should be changed by:

For a transistor,the current amplification factor is $\alpha = 0.8$. The transistor is connected in a common emitter configuration. The change in the collector current when the base current changes by $6 \, mA$ is.....$mA$.

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.

The current gain for a transistor working as a common base amplifier is $0.96$. If the emitter current is $7.2 \,mA$, then the base current is (in $\,mA$)

The collector current in a common base amplifier using $n-p-n$ transistor is $24\; mA$. If $80\%$ of the electrons released by the emitter are accepted by the collector,then the base current is numerically

In a transistor,the collector current varies by $ 0.49 \,mA $ and emitter current varies by $ 0.50 \,mA $. Current gain $ \beta $ measured is
