Answered & Verified by Expert
A transistor is operated in common emitter configuration at constant collector voltage \(\mathrm{V}_{\mathrm{c}}=1.5 \mathrm{~V}\) such that a change in the base current from \(100 \mu \mathrm{A}\) to \(150 \mu \mathrm{A}\) produces a change in the collector current from 5 mA to 10 mA. The current gain \((\beta)\) is:-

The correct answer is:
100
Current gas $=\beta=\frac{\Delta I_C}{\Delta I_B}$
$$
\begin{aligned}
& =\frac{(10-5) \mathrm{mA}}{(150-100) \mathrm{mA}}=\frac{5 \times 10^{-3}}{50 \times 10^{-16}} \\
& =10 \mathrm{C}
\end{aligned}
$$
$$
\begin{aligned}
& =\frac{(10-5) \mathrm{mA}}{(150-100) \mathrm{mA}}=\frac{5 \times 10^{-3}}{50 \times 10^{-16}} \\
& =10 \mathrm{C}
\end{aligned}
