Given that,

\mathrm{V_1=0.01 volt }

\mathrm{R_{\mathrm{l}}=1 \mathrm{k} \Omega=10^3 \Omega }

\mathrm{\therefore I_b=\frac{V_1}{R_1}=\frac{0.01}{1 \times 10^3}=0.01 \times 10^{-3} \Omega=0.01 \mathrm{~mA} }

\mathrm{Further, \mathrm{I}_{\mathrm{c}}=\beta \mathrm{I}_{\mathrm{b}}=50 \times 0.01 \mathrm{~mA}}

\mathrm{=0.5 \mathrm{~mA}=500 \mu \mathrm{A}}
