Engineering Black box which contains 5x 1ohm resistors

Click For Summary
The discussion revolves around determining the configuration of five 1-ohm resistors within a black box with three terminals, A, B, and C. Measurements taken with an ohm-meter show the resistances between the terminals: 1.5 ohms between A and B, 3 ohms between B and C, and 2.5 ohms between A and C. Participants analyze these values to deduce the arrangement of the resistors. The conversation emphasizes the importance of verifying solutions independently. Ultimately, the focus is on understanding the resistor configuration based on the given resistance measurements.

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.
 
Thread 'Why wasn’t gravity included in the potential energy for this problem?'
I’m looking at the attached vibration problem. The solution in the manual includes the spring potential energy but does NOT include the gravitational potential energy of the hanging mass. Can someone explain why gravitational potential energy is not included when deriving the equation of motion? I tried asking ChatGPT but kept going in circles and couldn't figure out. Thanks!
