Homework Help: Mesh Analysis

  1. Aug 10, 2008 #1
    Hello everybody on the physics forum, i was just looking for someone to point me in the right direction and tell me if my equations are right
    1. The problem statement, all variables and given/known data
    Determine the current though the resistance R2 by mesh analysis

    3. The attempt at a solution
    Ok, this is what i have so far:
    Loop 1: I1=1A
    Loop 2: R3(I2-I3)+R4(I2-I1)=12
    Loop 3: -R1(I3-I1)+R3(I3-I2)-R2I3=0
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Yeah it looks ok to me. Just solve for I2 and I3.

    In loop 3 all signs should be the same (positive or negative)
