Homework Help Overview
The discussion revolves around determining the total resistance in a circuit, with participants addressing issues related to the circuit diagram and the configuration of resistors.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants question the clarity of the circuit diagram and the points between which resistance is to be measured. There are discussions about the potential need for circuit simplification and the use of delta-Y transformations. Some suggest practical approaches, while others express uncertainty about the symmetry of the circuit.
Discussion Status
The discussion is ongoing, with participants providing feedback on the clarity of the circuit representation and exploring different methods for calculating total resistance. Some guidance has been offered regarding circuit simplification, but no consensus has been reached on a specific approach.
Contextual Notes
There are noted issues with the circuit diagram, including missing details and potential short-circuits, which may affect the ability to accurately determine total resistance.

You can't.
1. the picture does not show a circuit.
2. the picture does not show the two points that the resistance is to be taken between.
3. there appears to be a short-circuit between the left and right-most extreme nodes.
Once the above issues are sorted out - you will find the total resistance by simplifying the circuit. It can help to redraw it.

Thank you for the scrutiny. Is this satisfactory now? I am sorry I there are still errors to tend to in the diagram, I hope I was able to convey enough information this time
Total resistance between nodes A and B

I don't see any symmetry that would help you out here so it seems to me you'll just have to do a ton of delta-Y transforms and simplify the circuit bit by bit. Looks to conceptually trivial but VERY messy to actually carry out.

I suggest a box of assorted precision-resistors and a good ohmmeter.

I'm tempted to say "about 2 ohms".
There is a 1 and a 2 "in series" between a and b with mostly higher values "in parallel".
If you model it as a 1+2 in parallel with a 3+4+5 you get about 2.4 Ohms.
