Thevenin's Theorem

  1. Nov 4, 2012 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    Vth = Isc * Rth

    3. The attempt at a solution

    I'm not sure what those triangles mean but I assume it means they belong to the same node so I redrew as such.
    After that I found the Rth to be Rth = [itex]\frac{2R*R}{3R} + R = \frac{5}{3}R[/itex]

    Edit : I found Isc = 0.2 A
    and Voc = 1/3 V

    Am i doing it correctly?

    Thanks

    The triangles signify circuit ground, so yes, they are the same node

    To check your work, see what the short circuit current would be and what the open circuit voltage would be at the output in both cases. If they agree, then you have the right answer.

    Yes, your value for the resistance is correct, although since you know R=10, you don't need to express it in terms of R.
