The discussion revolves around the difficulty in solving a problem related to determining the currents I1, I2, and I3. Participants emphasize the importance of applying Kirchhoff's laws, specifically the need to write down two voltage loop equations. The original poster expresses challenges due to language barriers after moving from Hong Kong and taking a physics class in English. Ultimately, it is concluded that there is insufficient information to arrive at a unique solution for the currents. The thread is closed, indicating that the issue may not be complex enough for advanced physics analysis.

Homework Statement
Determine the currents I1, I2, and I3.
Relevant Equations
I2 + I3 = I1
I’m having trouble solving this one problem.
Sorry I’m really struggling with currents and I don’t know where to start.
 
Physics news on Phys.org
We don't know whether the currents are equal.
What did you learn about Mr Kirchooff?
 
you need to write down the two voltage loop equations...

Yea sorry I just looked back at my notes and a video in my language. Unfortunately, I moved from Hong Kong and taking a physics class in English. English isn't my strongest language
 
Thread closed. There is not enough information to get to a unique solution, and this is not advanced physics.
 
Thread 'Correct statement about size of wire to produce larger extension'

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
