Homework Help: Using Kirchhoff's law for nodes A,B,C and D and for the circuits find the system of

  1. Oct 31, 2011 #1
    1. The problem statement, all variables and given/known data
    Using Kirchhoff's law for nodes A,B,C and D and then Kirchoff's law for the circuits around the main building, the annex and the warehouse, write a system of seven equations that could be solved for the currents I1, I2, I3, I4, I5, and I6

    I get (NOTE**the I are capital i, not one)

    3. The attempt at a solution

    I1-I2-I3=0
    I3-I4-I6=0
    I4-I5+I6=0
    -I1+I2+I3=0
    10I1-20I2=400
    10I4-RI6=0

    My answer seems to be wrong, please help!

    Thanks
