Homework Equations
here's what the book says
i3(25 ohms) = 12 V
i2(15 ohms) = 6.0V + 12 V
i1 = i2 + i3
The Attempt at a Solution
i have tried over and over again on hoow they got the equations from but i don't understand.
where did i3 come from there are only 2 resistors. so only 2 current.
i just don't understand kirchhoff loop rule, is there any place where i can a ismple explanation because the book DOES NOT HELP
