Electronic Question:
Divide a square resistor into nine parts on average and dig out the middle one. What's the resistance of the remained parts now?
I want to pose a image to explain the situation, but I don't find the place which can let me do it.
I add something: the current distribution in a complex conductor is not a simple series-parallel relationship, so it is difficult to calculate the current distribution. Whether it should have a premise that the solution is the uniform isotropic bulk material, in this caseļ¼to calculate the resistance under DC.
My fellower abvise me to make a clear knowledge system of resistors, thus I have to find more info about resistors, toady I read an article about it, its has many theories and some examples, but it not enough. Although it has theories to introduce resistors, the examples to support these theories are rare. So is there anyone can give some reference materials like this https://www.kynix.com/Blog/316.html, be specific, what's more, giving examples to make me understand well.
Thank you in advance.

youneed to assume voltage at one of the vertex be V and at the opposite vertex be 0. now, the square resistor circuit will be simplified into series-parallel network. By eliminating no current branches, it will reduce to series-parallel combination of only six resistors (instead of
. now the required resistance can be be easily calculated.then a similar request worked. in the end, everything was decided by formulas and calculations. in the comments, you can see.
