Using the maximum power transfer theorem

  1. Oct 14, 2016 #1
    1. The problem statement, all variables and given/known data
    Using the maximum power transfer theorem, find the value of R which will result in the maximum power being delivered to R.

    2. Relevant equations
    P_max= (V_oc)^2/4(R_th))
    R_L=R_th
    P_RL=(V_th/(R_th+R_L))^2*R_L

    3. The attempt at a solution
    I have no clue where to even begin with changing this circuit to its Thevenin equivalent. I feel like there are 2 unknowns here (power and resistance) and I don't even know where to get started with trying to solve for R.

    What is the usual procedure for finding a Thevenin equivalent?
