Resistor Network Circuit Analysis

  1. Mar 13, 2015 #1
    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. The problem statement, all variables and given/known data. 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.



    2. Relevant equations


    My equations are on the scans.

    3. The attempt at a solution

    I definitely attempted the solution on the scans attached.

    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 ?
