Another question form my paper i sat today, again I think this is very elementary but I am just slightly confused. Considering I want to continue in electrical engineering in the future i guess it's important I get things like this right. My question is to work out, I1, and i2, plus the voltage against the 3kOhm resistor. Now I am not sure I have obtained two values for i1, 2.5A and than for total 3.37mA. Not sure what is right, I understand essentially where I need to begin but lost along the way! -.-

Thanks all
