AI Thread Summary
Applying Kirchhoff's rules is suggested to solve circuit problems involving unknown currents and resistances, but insufficient information complicates the process. The direction of the ammeter current remains ambiguous without additional data, leading to multiple possible solutions. Participants emphasize that the lack of specific details makes it challenging to arrive at a definitive answer. The discussion highlights the importance of having complete information for accurate circuit analysis. Ultimately, the inability to determine certain variables limits the problem-solving approach.

https://www.physicsforums.com/attachments/267955 I think i should apply kirchkoff rules so I can find i1,i2,i3 R1,R' but I don't have enough information and I don't know how to have those informations .What is your ideas?

In which direction is the ammeter current?
If that is not given, there are multiple answers to this problem.

It's arbitrary I guess, because i don't have the information

Do NOT edit/delete your post after you have received replies. That is tantamount to cheating, and is not allowed on the PF. Check your PMs. Thread is locked.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
