Discussion Overview
The discussion revolves around calculating the total resistance in a circuit, with participants seeking assistance and clarification on how to approach the problem. The scope includes technical explanations and problem-solving strategies related to circuit analysis.
Discussion Character
- Homework-related
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants suggest that resistances connected between the same two points can be treated as parallel resistances, proposing to find equivalent resistances for those configurations.
- One participant expresses difficulty in solving the problem, indicating it is their first encounter with this type of circuit analysis.
- Another participant advises against providing direct solutions, emphasizing the importance of learning through the problem-solving process and suggesting a method to redraw the circuit for clarity.
- Specific resistances in the circuit are mentioned, including sets of 6Ω, 12Ω, and 4Ω resistors in parallel, as well as pairs of 2Ω resistors in series.
- A formula for calculating resistors in parallel is referenced, although not explicitly stated in the discussion.
Areas of Agreement / Disagreement
Participants generally agree on the approach to solving the circuit problem, although there is no consensus on the specific calculations or methods to be used, as some participants are still struggling with the concepts.
Contextual Notes
Some participants have not yet provided their working or attempts at the problem, which may limit the discussion's depth regarding specific calculations or methodologies.
Who May Find This Useful
This discussion may be useful for students or individuals new to circuit analysis, particularly those seeking guidance on calculating total resistance in complex circuits.

Everything that is connected with wires can can be joined in a single point.
Now every resistance that's between two of these points will be parallel with any other resistance that's between the same two points. For example between green and red you have 3 resistances in parallel, which you can replace by their equivalent.

can i please have the solution for this question because i have difficulty getting the answer because it's the first time I'm doing this type of problem.
Thanks in advance.
Thanks in advance.

we try to avoid giving direct solutions, you don't learn anything that way ;)
redraw your circuit using willem2's suggestion.
You will see initially, you have 2 sets of parallel resistors the upper 6Ω, 12Ω and 4Ω ones
and the lower 2 lots of 4Ω ones
solve those 2 sets of parallel values
then you have a pair of 2Ω ones in series that you can get a total value for
Redraw the circuit now with those calculated totals and then do any other series or parallel calculations :)
here's a formula for calculating resistors in parallel ...
have some attempts to work it out, show us your working and us guys will guide you through the process :)
