Homework Help Overview

The discussion revolves around analyzing a complicated resistance circuit, specifically identifying its configuration as a Wheatstone bridge. Participants are exploring the setup and attempting to clarify their understanding of the circuit's arrangement and behavior.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to break down the circuit but questions the correctness of their configuration. Some participants suggest using Kirchhoff's Current Law (KCL) equations as a method to analyze the circuit, while others reflect on the identification of the Wheatstone bridge.

Discussion Status

The discussion is active, with participants providing hints and suggestions without offering direct solutions. There is recognition of the circuit's configuration, and some participants are exploring different approaches to analyze the circuit effectively.

Contextual Notes

There is mention of homework rules that restrict helpers from providing direct solutions, emphasizing the need for hints and guidance instead. Additionally, the original poster's lack of labeling in their circuit diagram is noted as a potential source of confusion.

I tried to break it down to:

But apparently it is incorrect, can someone tell me the correct configuration? And explain too! Thanks :)
(Please do not give ambiguous "hints").

Oh nevermind just realized this is is a wheatstone bridge, silly me

LOL. How about an unambiguous hint? Like using KCL equations to solve it. There may be a trick that you can use, but if you don't see the trick pretty quickly, just doing the KCL equations and solving should get you the answer. And for a circuit this simple, The KCL equations are fairly easy.

Oh, never mind then. :smile:
 
Helpers are not allowed to directly provide solutions to homework questions. They can only offer hints, suggestions, or point out mistakes or correctly done parts in your work.

What makes you say that your rearrangement is wrong? The only problem I can see would be if you incorrectly locate the 20 Ω resistor on the figure (you didn't label any of the the resistors, so I can't be 100% sure that you've got that right).

Edit: Just saw the OP's latest post, correctly identifying the circuit configuration. So never mind :smile:
