Find the equivalent resistance between two points in terms of R

Click For Summary

Homework Help Overview

The discussion revolves around finding the equivalent resistance between two points in a circuit, specifically in terms of a variable R. Participants are exploring the concepts of series and parallel resistor configurations.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are encouraged to share their understanding and attempts at solving the problem, with some expressing difficulty in determining the configuration of resistors as either in series or parallel.

Discussion Status

There is ongoing dialogue about the necessity of showing credible effort before receiving help. Some participants have offered hints regarding the criteria for identifying series and parallel resistors, while others emphasize the importance of using LaTeX for clarity in mathematical expressions.

Contextual Notes

Participants are reminded of the forum's rules regarding homework help, specifically the requirement to demonstrate effort and the prohibition against providing complete solutions.

According to our rules, to receive help, you need to show some credible effort towards answering the question(s). How about telling us what you do know and how you would approach this problem?

Please read, understand and follow our homework guidelines, especially item 4, here
https://www.physicsforums.com/threads/homework-help-guidelines-for-students-and-helpers.686781/
I attempted to solve the problem using the formulas I have provided above, but my answers are not matching, also I tried to search for similar problems in the internet but found nothing
 
OK, but "I tried and didn't get anywhere" is not sufficient attempt at a solution. Please post what you tried and what you got. We would prefer that you use LaTeX which is to learn. Click the link "LaTeX guide", lower left, to see how to do it.
 
New user is reminded that they always need to show their best efforts on schoolwork problems before we can offer tutorial help.

Thank you, I will learn how to do it. I am just learning and new here, so would appreciate solution for my problem, the problem seems very unique for me as it's really challenging for me to determine whether the resistors are in parallel or in series, otherwise I wouldn't post it here.

We don't supply solutions, only hints and you must make and show an effort to use them. So here are some.

What are the criteria for resistors being in series?
What are the criteria for resistors being in parallel?
Do you see any resistor combination in this circuit that satisfies these criteria? If so identify them.

As has been explained to you several times in this thread so far, we do not give solutions to schoolwork questions. We can provide hints, ask probing questions, find mistakes, etc., but the student must do the bulk of the work on schoolwork questions. Please see the PF Rules link under INFO at the top of the page.

This thread will remain closed. Please start a new thread and show your work if you want tutorial help. Thank you.
