(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For the circuit shown in the figure below, calculate the current I_{4}through the 1.94Ω resistor.

As shown, R1 = 4.05Ω, R2 = 8.11Ω, R3 = 6.17Ω, R4 = 1.94Ω, I1 = 2.97A and E1 = 12V

2. Relevant equations

V=IR

ƩI in a junction = ƩI out of a junction

ƩV in a loop = 0

3. The attempt at a solution

I_{1}R_{1}+I_{1}R_{2}-E_{1}+ I_{2}R_{3}=0

I_{1}= I_{2}+ I_{4}

So

I_{4}=I_{1}- ((-(I_{1}*R_{1}) - I_{1}R_{2}+ E_{1})/R_{3})

I don't have many tries left, so I want to know if my analytical solution is correct, and if I've just been making my error plugging the numbers back in.
