(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given the drawing, calculate the current going through the 2Ω Resistor and then calculate the difference in electric potential from point a to b.

2. Relevant equations

V = IR

juction rule:

ƩI = 0 = I_{in}- I_{out}

ƩV = 0

3. The attempt at a solution

Well, I attempted to draw all the currents. The Green is from the 3Volts on the bottom, the orange is from the 12V on the top. I would think that I could use a sum of the different V=IR equations (12/4 + 3/2 + 3/2), but 6 is not the answer. I'm pretty lost clearly.
