Homework Help Overview

The discussion revolves around setting up equations for electrical circuit problems, specifically involving Kirchhoff's rules and the analysis of circuit loops.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need to establish simultaneous linear equations based on circuit loops. There is a request for clarification on how to set up these equations, indicating a lack of confidence in the subject matter.

Discussion Status

Some guidance has been offered regarding the use of Kirchhoff's rules to set up equations, but there remains uncertainty about the initial setup and approach. Participants are exploring different aspects of the problem without reaching a consensus.

Contextual Notes

There are indications of missing information, such as diagrams and attachments that are not accessible to all participants. Additionally, there are reminders about forum etiquette and posting guidelines that may affect the flow of discussion.

I need your help
 
Physics news on Phys.org
1) The link doesn't work.
2) Do not post the same question in multiple forums.
3) Read the sticky at the top of the forum. (The one that says "Read This Before Posting".)
 
Please help

Please help me solve this question

the attachment is there

Isnt there an upload attatchment button on here anyway?
EDIT: your one step ahead of me
and click the submit button only once O.O

There are three different loops, so you can set up three simultaneous linear equations with the Kirchoff's rules. The total potential difference as you traverse a loop is zero.
So show us where you are stuck!
 
The truth is i don't know how to set up the equation, I'm simply weak in electric. Sorry
