Homework Help Overview

The discussion revolves around analyzing a resistor network circuit, where the original poster seeks assistance with calculating various electrical parameters such as equivalent resistance, current through the battery, current through each resistor, voltage across each resistor, and power used by each resistor. The problem involves multiple resistors with specified values and a voltage source.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster expresses uncertainty about their calculations and seeks clarification on their approach. Some participants question the values of the resistors, specifically R3, and whether the voltage of the battery is correctly stated. Others provide feedback on the equivalent resistance calculation.

Discussion Status

The discussion is ongoing, with participants actively questioning the values of the components and the calculations presented. There is a mix of interpretations regarding the resistor values and the battery voltage, indicating that multiple perspectives are being explored without a clear consensus.

Contextual Notes

Participants are working with a diagram that has inconsistencies in resistor labeling, which may affect the analysis. The original poster has attached scans of their work, indicating a need for clarification on their calculations and assumptions.

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 ?
