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 ______.
Numerical value type. Enter your answer.
Answer: 200
$$\beta = \frac{\Delta I_C}{\Delta I_B} = \frac{(4 - 2)\ \text{mA}}{(20 - 10)\ \mu\text{A}} = \frac{2\times10^{-3}}{10\times10^{-6}} = 200$$
