Find I0 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.
