## Homework Statement

http://imageshack.us/a/img210/3330/homeworkprob15.jpg

Find I

_{0}in the network.

(The middle resistor value was not given)

## Homework Equations

V = IR

Voltage Division:

(Voltage across series resistor) = [(resistance) / total series resistance)](total input V)

Current Division (for 2 parallel resistors):

(current across parallel resistor) = [(other resistor) / (sum of parallel resistors)](total incoming current)]

Parallel resistors = (1/R1 + 1/R2)

^{-1}

Series Resistors = R1 + R2

Delta Y conversion and back for resistors

## The Attempt at a Solution

I really do not know where I should start.

Other than all I can do being to simplify the 8 and 4 ohm resistors to 12 ohm. But then there's still that unknown resistor in the middle.

I don't see how it would help to use y to T or the other way around to help.
