A transistor has an ${\mathrm{I}}_{\mathrm{E}}$ of $0.9 \mathrm{mA}$ and implication factor of $0.98$. What will be the ${\mathrm{I}}_{\mathrm{C}}$?

In CB configuration, the value of $\mathrm{\alpha }=0.98 \mathrm{A}$. A voltage drop of $4.9\mathrm{V}$ is obtained across the resistor of $5 \mathrm{K\Omega }$ when connected in collector circuit. Find the base current

In a common emitter amplifier, when a signal of $40 \mathrm{mV}$ is added to the input voltage, the base current changes by $100 \mathrm{\mu A}$ and emitter current changes by $2.1 \mathrm{mA}$. The trans-conductance is
