A transistor is operated in common emitter configuration at constant collector voltage Vc=1.5V such that a change in the base current from 100μA to 150μA produces a change in the collector current from 5mA to 10mA. The current gain (β) is

In a common emitter (CE) amplifier having a voltage gain G the transistor used has transconductance 0.03 mho and current gain 25. If the above transistor is replaced with another one with transconductance 0.02 mho and current gain 20 the voltage gain will
