In a silicon transistor, the base current is changed by $$20$$ μA. This results in a change of $$0.02$$ V in base to emitter voltage and a change of $$2$$ mA in the collector current. The transistor is used as an amplifier with the load resistance of $$5$$ kΩ. The change in output voltage across load is

Question

In a silicon transistor, the base current is changed by $$20$$ μA. This results in a change of $$0.02$$ V in base to emitter voltage and a change of $$2$$ mA in the collector current. The transistor is used as an amplifier with the load resistance of $$5$$ kΩ. The change in output voltage across load is
