While a collector to emitter voltage is constant in a transistor,the collector current changes by $8.2 \, mA$ when the emitter current changes by $8.3 \, mA$. The value of forward current gain $h_{fe}$ is

In a transistor,the base is very lightly doped as compared to the emitter because by doing so:

In a common emitter configuration,an $N-P-N$ transistor is connected. The current gain of the transistor is $100$. If the collector current changes by $1 \ mA$,by how much will the emitter current change in $mA$?

In a transistor circuit, if emitter and collector connections are interchanged, then:

In a common emitter amplifier,the current gain is $62$. The collector resistance and input resistance are $5\,k\Omega$ and $500\,\Omega$ respectively. If the input voltage is $0.01\,V$,the output voltage is $..........\,V$.

$A$ transistor is connected in common emitter $(CE)$ configuration. The collector supply is $8\ V$ and the voltage drop across a resistor of $800\,\Omega$ in the collector circuit is $0.5\ V$. If the current gain factor $\alpha$ is $0.96$,find the base current in $\mu A$.
