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

For the circuit in the figure, determinei_{1}to i_{5}

http://i55.tinypic.com/dokoc5.png

2. Relevant equations

current division: i_{n}= (R_{equivalence}/ R_{n}) * i_{total}

R_{equivalence in parallel}= R1*R2 / R1+R2

3. The attempt at a solution

|| (parallel), and +s (series)

1ohms || 2ohms = R_{eq1}

R_{eq1}|| 4ohms = R_{eq2}

R_{eq2}+s 3ohms

However, note that current i_{3,4,5}are present. Parallel elements do not share the same current. I have trouble applying the current division.

If I assume I am only taking i3, i4, and i5, and let i_{3}be the total current at that particular region, then the R_{eqv}is (2*1)/2+1 meaning 2/3

Then which R_{n}should I take?

The formula for current division is mentioned above.

Please let me how to solve this problem that involves multiple currents going around.

Thank you.
