Homework Help: Thevenin's equvalent circuit of the network?

  1. Jul 6, 2015 #1
    1. The problem statement, all variables and given/known data
    thevenin's equvalent circuit of the network

    2. Relevant equations
    thevenin's voltage
    thevenin's impedance

    3. The attempt at a solution
    using nodal analysis i tried to find thevenin voltage but the dependent source and the dependent variable troubling me! IMG_20150706_113824.jpg

    I think the best way to work out how to do these problems is to 'cheat' and that is, start with the correct answer.
    Then work backwards to see how the answer was got to.

    Then work forwards from the beginning to see if you can get the correct answer.

    The reason for doing it this way is because a lot of time can be spent going down blind alleys (which can sometimes be useful, but often is frustrating).

    I recommend downloading a decent circuit simulator. A good free on is QUCS.

    You can build your circuit as drawn and measure currents and voltages at all points in the network.

    Then try to work out on paper, and see if you can match the correct result
