Homework Help Overview

The discussion revolves around solving current circuit problems, specifically focusing on the application of Kirchhoff's rules. Participants express concerns about insufficient information to determine current values and resistances.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to apply Kirchhoff's rules but questions how to obtain the necessary information. Some participants inquire about the direction of the ammeter current, noting that without this information, multiple interpretations exist.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the problem. There is a recognition of the ambiguity due to missing information, and some guidance is offered regarding the implications of arbitrary assumptions.

Contextual Notes

Participants highlight the lack of specific details regarding the circuit setup, which affects their ability to apply the relevant equations effectively. There are reminders about the forum's rules regarding post editing after receiving replies.

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.
