Homework Help: Wye - Delta conversion and Mesh Analysis

  1. Sep 19, 2010 #1
    1. The problem statement, all variables and given/known data

    a) Use Y-Δ transformation to simplify the circuit in Figure 2-a to that in Figure 2-b and find the elements and values of Z1, Z2 and Z3

    b) Use mesh analysis for the circuit in Fig. 2-b to calculate I1 and I2

    Here are the circuits.


    2. Relevant equations

    3. The attempt at a solution

    a) I'm not sure what to do to be honest.

    Do I convert the delta to wye form?

    So each 'branch' be equal to (-39j)(-39j)/(-39j-39j-39j)= -12j?

    So now would I have the three branches with -12j and 12j+9Ω= 9Ω ?



    And that's about all I can do.
