Here assume conduction voltage of diode is $V_{?}=0.7\mathrm{V}$ and for the switching transistor $V_{BE}(on)=0.7\mathrm{V}$ and ${?}_F$ is very large. Design the street light control circuit shown in the above figure such that the switching voltage is $V_S=2\mathrm{V}$ and the hysteresis widtl is $200\mathrm{mV}$. Assume $V_H=12\mathrm{V}$ and $V_L=?5\mathrm{V}$. Find the resistances in $k?$. You can assume the value of one resistance. $R_1$ $R_2$ Find the value of $V_{REF}$ in $V$. Suppose, the current through resistance $R$ is $150?A$ when $v_O=V_H$ and relay switch resistance is $330?$. Find the value of $R$ in $k?$.
