JEE PYQ: Semiconductors Question 5
Question 5 - 2021 (18 Mar 2021 Shift 2)
The typical output characteristics curve for a transistor working in the common-emitter configuration is shown in the figure. When $V_{CE}$ is 10 V and $I_C = 4.0$ mA, then value of $\beta_{ac}$ is ______.
Show Answer
Answer: 200
Solution
$\beta = \Delta I_C / \Delta I_B = (2 \times 10^{-3})/(10 \times 10^{-6}) = 200$.
