Find voltage for circuits with buffer amp

  1. Apr 22, 2014 #1
    1. The problem statement, all variables and given/known data

    impedance2_zps2f19a33b.jpe

    2. Relevant equations

    3. The attempt at a solution
    I first found Vab which was 10 by using voltage division on the first device. By connecting CD to AB, the equivalent resistor is 80// 20, 16? I am not sure where to go from here.

    Your life would be made easier if you first reduced Device #1 to its Thevenin equivalent and Device #2 to a single equivalent resistance. For part (2) draw the resulting circuit using your simplified device models.
