To use a transistor as an amplifier,

The voltage gain and current gain of a transistor amplifier in common emitter configuration are respectively $150$ and $50$. If the resistance in the base circuit is $850 \Omega$, then the resistance in the collector circuit is: (in $\Omega$)

In a transistor,which of the following statements regarding the physical dimensions of its regions is correct?

In a transistor, the base current is $10 \mu A$ and the emitter current is $1 \text{ mA}$. Then, the collector current is: (in $\mu A$)

The value of $I_c$ for the configuration shown is in $mA$.

$A$ transistor connected in common emitter mode has a load resistance of $5 \, k\Omega$. If the input peak voltage is $5 \, mV$ and the current gain $(\beta)$ is $50$, find the voltage gain.
