In a common emitter configuration of a transistor, the voltage drop across a $500 \mathrm{\Omega }$ resistor in the collector circuit is $0.5 \mathrm{V}$. If the current gain is $\mathrm{\alpha }=0.96$, the base current is $\frac{1}{6N} \mathrm{mA}$ then $N$ is :-

For given $CE$ biasing circuit, if voltage across collector-emitter is $12 \mathrm{V}$ and current gain is $100$ and base current is $0.04 \mathrm{mA}$ then determine the value collector resistance $R_c$ in ohm.
