Resistor Network Circuit Analysis

[Dhooy7]

Could someone help me with number 1. I think I did it wrong. I attached the diagram with the labels. On the original one the resistors aren't labeled, but I separately labeled them on my diagram.

1. R1=1.0 ohms
R2=3.0 ohms
R3=5.0 ohms
R4=12 ohms
R5=2.0ohms
R6=4.0 ohms
R=0.2 ohms
Vbatt=12.0 V

1. Homework Statement . I need to do determine the following:
a. Equivalent reistance
b current through the battery
c. The current through each resistor
d. the voltage on each resistor
e.the power used by each resistor

I really suspect I did something wrong.

Scan 11 is with the resistors labeled and breaking them down.
Scan 14 and 15 is of my work. If you can figure out what I did wrong that would be great!

Image 1 is of the initial problem.

Homework Equations

My equations are on the scans.

The Attempt at a Solution

I definitely attempted the solution on the scans attached.

I need help ASAP. Thanks!

Is R3 5 Ohms as you've listed in the problem statement or 6 Ohms as shown on the diagram?

Assuming R3 = 6Ohms..

Sheet 11 looks ok Req = 7.2R

Is Vbat 12V or 8V ?
