In a common emitter (CE) amplifier having a voltage gain G, the transistor used has transconductance $\displaystyle 0.03$ mho and current gain 25. If the above transistor is replaced with another one with transconductance $\displaystyle 0.02$ mho and current gain $\displaystyle 20$, the voltage gain will be :
Official answer
(1)
$\displaystyle \frac{2}{3} \mathrm{G}$
