Question
For a constant collector-emitter voltage of 8V, the collector current of a transistor reached to the value of 6 mA from 4 ma, whereas base current changed from 20 $\mu \mathrm{A}$ to 25 $\mu \mathrm{A}$ value. If transistor is in active state, small signal current gain (current amplification factor) will be :
