Homework Equations


For parallel resistors: 1/R=1/R1 +1/R2

The Attempt at a Solution


I am sure the resistors are not in series but they also don't look convincing enough to be parallel. I am stuck.

You can draw them with a clearer arrangement, then some symmetry will be visible.
Alternatively, just check resistor by resistor: where is one side connected to? Where the other? Is this the same for any other resistor?

I've tried all that to no avail. Pls check the link.

That is not simplified, it is the same diagram as in the problem statement.

The 1 Ohm resistor got 100 Ohms for some reason?
