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
- A \(200\)
- B \(400\)
- C \(100\)
- D \(169\)
Answer & Solution
Correct Answer
(A) \(200\)
Step-by-step Solution
Detailed explanation
\(\beta=\frac{\Delta I _{ C }}{\Delta I _{ B }}=\frac{2 \times 10^{-3}}{10 \times 10^{-6}}\) \(\beta=\frac{1}{5} \times 10^{3}\) \(\beta=2 \times 10^{2}\) \(\beta=200\)
