Thanks Kitonum 19099 and sursumCorda 20.

Both methods solve this puzzle symbolically.

@Preben Alsholm It makes equation (7). And I want to solve this ODE in Eq.(7) by Maple.

Using laplace convertion, I can get the answer and can plot it.

## Thanks...

@acer Thanks show me the power of Maple.

@acer Thanks your follow up. I try to find the mimimum of the intersect.

@tomleslie x=45, y=45, intersect=2.117 may be the maximum of intersect. How to find this value by Maple?

Node 1 to 13 is 1/2 ohm made by one ohm, where each current is different.

## Surprisingly, both are planar:...

@dharr @Carl Love is right. Surprisingly, both are planar. I only know this very fameous math problem. I only know the answers and don't know how to solve. I rewrited this math problem to the electric circuit problem.

Same question except make two ohm by one ohms, each current must different.

## All currents are different and none of t...

@dharr Yes, "all currents are different and none of them are zero".
Please try to calculate the resistance of node 1 to 13. This is very good electrical engineering problem that without using computer math software, such as Maple, not only students but also professors can't solve.
