The input resistance of a silicon transistor is 100 Ω. Base current is changed by 40 μ A which results in a change in collector current by 2 mA. This…
The input resistance of a silicon transistor is $\displaystyle 100 \Omega$. Base current is changed by $\displaystyle 40 \mu \mathrm{~A}$ which results in a change in collector current by $\displaystyle 2$ mA. This transistor is used as a common emitter amplifier with a load resistance of $\displaystyle 4 \mathrm{~K} \Omega$. The voltage gain of the amplifier is :
