Circuit (equivalent resistance)

Click For Summary

Discussion Overview

The discussion revolves around finding the equivalent resistance in a circuit, focusing on the challenges of identifying series and parallel connections. Participants are exploring methods to simplify the circuit for analysis.

Discussion Character

  • Homework-related, Exploratory, Technical explanation

Main Points Raised

  • One participant expresses difficulty in simplifying the circuit and identifying series and parallel loops.
  • Another suggests marking junctions and potential to aid in visualizing the circuit connections.
  • A participant questions the necessity of considering potential in the context of simplifying the circuit.
  • There is a discussion about the behavior of potential across parallel and series sections, with one participant seeking further clarification on distinguishing between the two types of connections.
  • A suggestion is made to visualize moving a resistor to better understand the circuit layout.

Areas of Agreement / Disagreement

Participants are generally engaged in exploring the problem, but there is no consensus on the best approach to simplify the circuit or on the clarity of the concepts involved.

Contextual Notes

Participants express uncertainty about the identification of series and parallel connections, and there are unresolved questions regarding the role of potential in the analysis.

Req(series) = R1 + R2...
Req(parallel)=(1/R1+1/R2...)^-1

The Attempt at a Solution


I'm having problems understanding how to simplify this circuit.
There should be parallel and series "loops" to simplify but I'm having trouble seeing them.

Mark the junctions where potential is a . Consider a random voltage V , which is the potential in between the 2Ω and 3Ω resistors .

Now draw a fresh diagram , now marking a , b and V , and connecting resistors between the three appropriately . This should help in simplifying the circuit , making it easy to see the series and parallel connections .

Hope this helps .
 
Updated the image with the resistors numerated in red.

Do you have to consider potential?
 
Yes , the potential is what I mentioned in my previous post .
 
What i know is that potential stays the same across parallel sections and is summed up in series.

How does that help me if i can't distinguish which one is in parallel or in series?

Would you mind to explain a little further please, I'm kind of new to this.
 
Look at the bottom end of R2...imagine sliding it to the left and around the corner.
