what is the current through the 8 ohm resistor?

8 V

. empty space 8 ohm Res

. empty space . I_2

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
