Problem 4 For the circuit shown below: a) Use the voltage-division principle to calculate the voltage across $R_3$. Assume $v_s = 50 V$, $R_1 = 20 \Omega$, $R_2 = 30 \Omega$, and $R_3 = 20 \Omega$. b) Use the current-division principle to calculate the current through $R_2$. Assume $i_1 = 10 mA$, $R_1 = 5 k\Omega$, $R_2 = 12 k\Omega$, and $R_3 = 18 k\Omega$.
