A transistor is operated in common emitter configuration at V C = 2 V such that a change in the base current from 100 μ A to 300 μ A produces a change in the collector current from 10 mA to 20 mA .

Question

A transistor is operated in common emitter configuration at V C ​ = 2 V such that a change in the base current from 100 μ A to 300 μ A produces a change in the collector current from 10 mA to 20 mA . The current gain is
