Hello everyone i have the follwoing circuit:(adsbygoogle = window.adsbygoogle || []).push({});

http://www.webassign.net/hrw/hrw7_27-34.gif I need to find the Potential Difference between a and b. I found the current of R1 and R2, and the questions says:

R1 = 130 , R2 = 75 , and the ideal batteries have emfs E1 = 6.0 V, E2 = 5.5 V, E3 = 4.0 V.

R1 current = .042A

R2 current = .0467

Im confused on what I should add u using kricofs rule? like do i just say

Va = -E2 -E3+ R1*i2 + Vb

Va -Vb = -E2 -E3+ R1*i2

But there is a resistor that looks like paraellel, but is that R1 parellel to R2?
