## Homework Statement

For the circuit in the figure, determine

**i**

_{1}to i_{5}http://i55.tinypic.com/dokoc5.png

## Homework Equations

current division: i

_{n}= (R

_{equivalence}/ R

_{n}) * i

_{total}

R

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

## 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.
