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

The typical output characteristics curve for a transistor working in the common-emitter configuration is shown in the

The estimated current gain from the figure is

Correct answer

200

Step-by-step solution

$\beta = \dfrac{\Delta{I}_{C}}{\Delta{I}_{B}} = \dfrac{2 \times {10}^{- 3}}{10 \times {10}^{- 6}}⇒ \beta = \dfrac{1}{5} \times {10}^{3}⇒ \beta = 2 \times {10}^{2}$

$⇒ \beta = 200$
