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

Step-by-step solution

β = Δ I C Δ I B = 2 × 10 - 3 10 × 10 - 6 ⇒ β = 1 5 × 10 3 ⇒ β = 2 × 10 2 ⇒ β = 200
