A transistor is operated in common-emitter configuration at Vc = 2 V such that a change in the base current from 100 µA to 200 µA produces a change in the collector current from 5 mA to 10 mA. The current gain is:

[Solution from source] Current gain β = ΔIc/ΔIb = (10 − 5) mA/(200 − 100) μA = 5 × 10⁻³ A/10⁻⁴ A = 50. A value of 100 or more comes from mishandling the milli and micro prefixes. Answer (3).
