Hi I need some help trying to solve IO in this mesh current analysis problem. Element E is a 5 volt power supply with the + at the top. What I originally did....
Set mesh 1 (ia) in the left loop as
10=5000ia-10000ia+10000ib
and mesh 2 (ib) in the right loop as
5=10000ia-10000ib-4000ib
after algebraic manipulation I found ia=.004167a and ib=.006333. Then I subtracted ia from ib and thought io=-.002167. However, the book's answer was -.136ma. Please help!
