Using EL equation, $$L=\left(\frac{t^2}{\alpha}\dot{x}^2-\frac{c^2t^2}{\alpha}\dot{t}^2\right)^{0.5} \Longrightarrow \mathrm{constant} =\left(\dot{x}^2 -c^2 \dot{t}^2\right)^{-0.5} \left(\frac{t^2}{\alpha}\right)^{0.5} \dot{x}$$. Get another equation from the metric: $$ds^2=-\frac{c^2t^2}\alpha...

i think it's alright, i get the rough idea. Nice receiving your help, and thanks, anyways just curious, which university did you graduate from? :)

Have already done that, i just need confirmation and I am more than sure you have the capability to understand the diagrams I drew and verify.

then?

You mean this?

What do you mean by draw wires?

Okay I see but I'm lost how do I continue?

Um I'm sorry but why are the green nodes red?

Hmm, thanks for some interesting ideas. In the uploaded picture, I have highlighted the nodes, with same colour nodes have same voltage. I looked up online and found that we can treat the nodes as a parallel circuit, as in the cube resistor problem, and as you mentioned. So we can surely divide...

Hey there! I'm having some real trouble deciphering this complex resistor problem. I have heard of the Kirchhoff voltage and current rules and do know how to use them to solve some problems but I'm not sure how to apply them in this context, or if they are even used to solve this. As seen the...
