Thévenin's Equivalent

  1. Oct 19, 2014 #1
    1. The problem statement, all variables and given/known data

    Find the Thévenin's equivalent.

    2. Relevant equations

    V=IR

    3. The attempt at a solution

    I'm not sure if I need to take into account the internal resistance. And also, is finding thévenin's equivalent just calculating Rth and Vth?

    I'm really lost sorry.
    Many thanks.

    Yup, the internal resistance of the battery counts. Rth and Vth are what you're after.

    Your Rth looks good, but something went wrong with your final calculation of Vth. If you look at the resistors in the voltage divider you'd expect to see Vth = 1/2 of your v1...
