# Homework Help: Voltage, Resistance, and Current chart

1. The problem statement, all variables and given/known data
I have a chart here:

2. Relevant equations

I = V/R

3. The attempt at a solution

$I_{1} = \frac{24.0 V}{8.0 V} = 3.00 A$

$R_{1} = \frac{8.00 V}{3.00 A} = 2.67 Ω$

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.
