The discussion revolves around finding the equivalent resistance of a circuit composed of resistors, each with a resistance of 1 Ω. The original poster expresses confusion regarding their calculated equivalent resistance compared to a reference book's answer.
The discussion is active, with participants exploring various methods to approach the problem. Some have offered guidance on using symmetry and simplifying the circuit, while others question the assumptions made about current distribution and resistances. There is no explicit consensus on the correct approach or solution yet.
Participants note the complexity of the circuit and the potential for errors in algebraic manipulation. There is mention of the need for independent variables for certain resistors and the challenges posed by the circuit's symmetry.
Very neat, but in the context of the problem in post #1, wouldn’t it be computationally more arduous than using symmetry?Deli Zhang said:This article https://delizhang.blogspot.com/2015/04/the-formula-for-equicalent-resistance.html gives a formula for calculating the equivalent resistance of an arbitrarily complex circuit, and you can get the answer by following it without having to think about it.
