Use the technique of simplifying this circuit using equivalent resistances into smaller, simpler circuits. Given the following circuit: If $\mathrm{R}1=15?,\mathrm{R}2=36?,\mathrm{R}3=12?,\mathrm{R}4=24?,\mathrm{R}5=12?$ and $\mathrm{Vs}=15$ Volts, determine the circuit equivalent resistance (REQ) and the circuit current (I). Also calculate the branch currents through R2, R3, $\mathrm{R}4$, and R5, and the voltage drops across R1, R2, R3, R4 and R5.
