Homework Help: Kirchoff's Laws Current [Problem 1]

  1. Jan 21, 2015 #1
    1. The problem statement, all variables and given/known data
    Determine the currents I1, I2, and I3. R5 = 18[PLAIN]http://www.webassign.net/images/omegacap.gif. [Broken] Assume the internal resistance of each battery is r = 1.0 [PLAIN]http://www.webassign.net/images/omegacap.gif. [Broken]

    2. Relevant equations
    Kirchoff's Loop Rule: I1+I2+I3=0
    Kirchoff's Series Law?: V1+V2+V3=0

    3. The attempt at a solution
    I've tried a million things, but with no luck. I know I'm supposed to substitute the different equations, but I just can't seem to come up with the right answer.
