Homework Help: Superposition Question, electric circuits

  1. Oct 1, 2009 #1
    1. The problem statement, all variables and given/known data

    ^^^^ = resistor = 10 ohm
    <> = 3*Vab Dependent voltage. (the voltage equals 3 times Vab)
    0 = voltage source 4 v (inderpendant)
    o = Inderpendant Current source 2 A



    |--^^^^---<>---------a +
    | + + - |
    0 o Vab
    | - |
    |-----------------------b -

    Question asks, Find Vab (the voltage across a and b) using superposition



    2. Relevant equations
    Well theres lots, ohms, KCL, KVL etc,


    3. The attempt at a solution
    I want to attempt it, but i dont no how to break this down, as all the examples in the txt book dont have the dependant votlage source, and in the examples they are solving for a voltage across a resistor.

    Any ideas? thanks
    ps i also uploaded the image just incase the one above didnt work once posted

    What is the current through the 10 ohm resistor?
    What are the voltages at the two ends of this resistor?
