what is the current through the 2 ohm resistor?
what is the current through the 8 ohm resistor?
8 V

16 V
! = (-) side of battery
| = (+) side of battery
I_1 is on the 2 ohm branch (current going left to right)
I current going down (clockwise)
I_2 current going down (clockwise)
Is this setup right with correct sign conventions?
I_2=I+I_1
2 ohm res:
+8V-2I_1=0
8=2I_1
I_1=4 A
8 ohm res:
-8V-8I_2+16V=0
8V=8I_2
I_2=1 A
