Solving Circuits with Resistors: Finding Req and Applying the VIR Chart

Click For Summary
SUMMARY

The discussion focuses on solving circuits with resistors, specifically finding the equivalent resistance (Req) and applying the Voltage-Current-Resistance (VIR) chart. The user successfully calculated Req but encountered difficulties with the VIR chart, seeking confirmation on their approach. They utilized the properties of series and parallel circuits, along with the Loop Law, to derive voltage values for specific resistors. Clarification was requested regarding the problem statement and the context of the VIR chart.

The Attempt at a Solution


So far I haven't had any problems finding the Req. However, I am having trouble with the VIR chart. Can anyone confirm whether or not I did it correctly. My thought process was that I would work backwards from the Req knowing whatever is in series will have the same current and parallels have same voltage. I tried applying the Loop Law as well knowing those 2 properties.

For example, I know that R2345 is has a certain R but also has the same current as R1. Knowing this I I found the voltage for R2345 and divided by 2 to find the voltage for R234 and R5.

You don't have to post your own solutions, although they would help me figure out what's wrong, but I just need to know if I am on the right path using the following thought process.

Hi megaboy123, Welcome to Physics Forums!

It's not clear what the problem is. Can you provide a problem statement that describes what you are given and what is to be done or calculated? Set the scene for us? For example, is the VIR chart something provided as part of the problem, or something you filled out from another step that we don't see? Remember, none of us here are in your class or have seen your labs or assignments.
 
We seem to be missing a problem statement here. Please edit this and indicate what the problem is.
