Find the current in the bottom-most wire (the I5 current).
Kirchhoff's current and loop rules.
The Attempt at a Solution
Using Kirchoff's current and loop rules, I obtained:
I then substitued my results into my equation for I5 and used Kichoff's rules again to put I5 in terms of I1
Then I solved for I1 and used that to solve for I5.
Unfortunately, the answer in my book is 2.1 amps. I've worked this problem multiple times, and the only thing worse than doing all that algebra over and over again is getting a wrong answer each time. Can someone help me out here?
Also, I didn't see an intro section, so I guess I'll take care of that here. My handle is BadAnima, and I'm currently a freshman in university. My major is chemical engineering, but I'm not sure if I want to stay on this track or go into physics.
