Q83 / 90 · JEE Main 2021 (18 Mar Shift 2) · Physics

The typical output characteristics curve for a transistor working in the common-emitter configuration is shown in the figure.
The estimated current gain from the figure is

Correct answer: 200

Solution

$β = \frac{Δ I_{C}}{Δ I_{B}} = \frac{2 \times 10^{- 3}}{10 \times 10^{- 6}}$ $\Rightarrow β = \frac{1}{5} \times 10^{3}$ $\Rightarrow β = 2 \times 10^{2}$

$\Rightarrow β = 200$

Hence, the correct answer is 200.
