1. The problem statement, all variables and given/known data

What is the potential difference V_{ab} of point a relative to point b?

I found out earlier that the current in the top branch is 0.8 A

In the middle is 0.2 A

and at the bottom is 0.6A

2. Relevant equations

So V = IR - IR

3. The attempt at a solution

3*(0.8) - 4*(0.2) = 1.6V

But this isn't working for me...what am I doing wrong?
