In summary, the conversation discusses a black box with three terminals containing five 1-ohm resistors. The measured resistance between the terminals is 1.5 ohms for A-B, 3 ohms for B-C, and 2.5 ohms for A-C. The configuration of the resistors inside the box is determined through self-checking.

Homework Statement
I solved it but im not sure if correct, resistance circuit problem.
Relevant Equations
r1*r2/r1+r2 --> 2 parallel resistors.
r1+r2 --> seriel resistors.
You are given a black box with three terminals, as shown below. The box is known to
contain five 1-ohm resistors. Using an ohm-meter, you measure the resistance between the terminals to be the following:
A - B: 1.5 ohms
B - C: 3 ohms
A - C: 2.5 ohms
Determine the configuration of the five resistors inside the box.
So on the left side is the Terminal A, on the right side is B and below is C.

Why not?

ok i can now, for some reason it didnt work earlier

Yes, your solution is good, but checking it yourself is something that you need to learn.
