Question
A signal of $20 \mathrm{mV}$ is applied to common emitter transistor amplifier circuit. Due to this, the change in base current and the change in collector current are $20 \mu \mathrm{A}$ and $2 \mathrm{~mA}$. The load resistance is $10 \mathrm{k} \Omega$. The voltage gain is:(a) $20 \mathrm{~V}$(b) $10 \mathrm{~V}$(c) $50 \mathrm{~V}$(d) none of these
