Kirchoff's Equations

  1. Oct 16, 2008 #1
    1. The problem statement, all variables and given/known data

    Write six equations using the unknown currents I1, I2, etc.

    Circuit included as attachment.

    2. Relevant equations

    Ohm's law

    3. The attempt at a solution

    So I1, and I3 are fairly straightforward.
    [tex]I_{1}=\frac{X}{R_{1}}[/tex]
    and
    [tex]I_{3}=\frac{X}{R_{3}}[/tex]

    Now I get confused. Because the voltage divides, I am unsure of how to attain the equations for the remaining currents without using the mesh current method.

    Thank you for the help.

    Edit, and now I realize that I3 is not X/R3, but rather I3=I1, but my confusion still stands about the best way to retrieve 6 equations.

    Perhaps they want you to use Kirchoff's laws, as suggested by the problem title?

    Hint: Kirchoff's laws involve the various loops and nodes within the circuit.
