Attach a 450 mA current source between the terminals a–b in Fig. P3.6(a), with the current arrow pointing up.
a) Use current division to find the current in the 36 Ω resistor from top to bottom.
b) Use the result from part (a) to find the voltage across the 36 Ω resistor, positive at the top
c) Use the result from part (b) and voltage division to find the voltage across the 18 Ω resistor, positive at the top.
d) Use the result from part (c) and voltage division to find the voltage across the 10 Ω resistor, positive at the top
