## Homework Statement

Find the current in the bottom-most wire (the I

_{5}current).

## Homework Equations

[tex]

I=\frac{\Delta V}{R}

[/tex]

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 I

_{5}and used Kichoff's rules again to put I

_{5}in terms of I

_{1}

Then I solved for I

_{1}and used that to solve for I

_{5}.

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.
