1. The problem statement, all variables and given/known data the question can be found here: http://www.mailfreeonline.com/uploader/5731C3EE.jpg [Broken] 2. Relevant equations 3. The attempt at a solution i couldn't do parts a and b. part c: i added resistors in parallel and somehow got a value that Vo = 9.33V (part of the circuit above the 2A current source simplifies to a current sources of 5A and the lower part to a resistor of 4/3). surely i should only be able to find Vo in terms of Io... could someone please show me how to do part (a) and confirm my answer for part (c)?
