A transistor is operated in common emitter configuration at V_CC = 2 V such that a change in the base current from 100 μA to 300 μA produces a change in the collector current from 10 mA to 20 mA. The current gain is
Q1. A transistor is operated in common emitter configuration at V_CC = 2 V such that a change in the base current from 100 μA to 300 μA produces a change in the collector current from 10 mA to 20 mA. The current gain is
Answer: 50
Explanation: Using the formula β = ΔI_c / ΔI_b, we get β = (20 - 10) mA / (300 - 100) μA = 50.
