Homework Help Overview

The discussion revolves around a chart related to voltage, resistance, and current, with a focus on applying Ohm's law and Kirchhoff's voltage law (KVL) to analyze a circuit. Participants are exploring how to fill in the chart based on given values and relationships.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to apply Ohm's law but expresses uncertainty about how to proceed further with the chart. Some participants suggest using KVL and question the original poster's understanding of the law, while others seek clarification on KVL itself.

Discussion Status

The discussion is ongoing, with participants providing hints and clarifications regarding KVL and its application. There is an acknowledgment of gaps in the original poster's knowledge, and some guidance has been offered to help navigate the problem.

Contextual Notes

The original poster indicates that KVL has not been covered in their text, which may limit their ability to apply the concept effectively in this context.

Homework Statement


I have a chart here:

Homework Equations



I = V/R

The Attempt at a Solution



[itex]I_{1} = \frac{24.0 V}{8.0 V} = 3.00 A[/itex]

[itex]R_{1} = \frac{8.00 V}{3.00 A} = 2.67 Ω[/itex]


I'm stuck at how to progress on filling this up any further. Any hints?

Thanks :)

You've specified V/V for I1. That's not Ohm's law.

Start by using KVL around the loop, treating the R2||R3 combination as a single item (maybe call it "Rp"); what's the potential drop across it?

Oops, my bad, should have noticed that.

What's KVL?

KVL is Kirchhoff's voltage law; the sum of the potential changes around a closed path is zero.

Oh, ok, we haven't covered that yet in my text.
