1. The problem statement, all variables and given/known data http://img245.imageshack.us/my.php?image=physicsef4.jpg 2. Relevant equations The change in Voltage = 0. 3. The attempt at a solution Ok I have no clue where the loops go from. I want to say something like the current for I1 starts at the 10V battery in the middle and the current would look something like this: 8ohm + 2ohm +15v +I1 +3ohm - I2 = 0..... I just really don't understand these problems and could use some help thanks.
