Find the equivalent resistance in a circuit

Click For Summary

Homework Help Overview

The discussion revolves around finding the equivalent resistance in a circuit involving multiple resistors, specifically two sets of resistors with values of 4 Ohms and 2 Ohms. Participants are exploring the configuration of these resistors and how they relate to each other in terms of series and parallel arrangements.

Discussion Character

  • Conceptual clarification, Assumption checking, Mixed

Approaches and Questions Raised

  • Participants discuss the arrangement of the resistors, with some asserting that certain resistors are in series while others question whether they are in parallel. There is uncertainty about how to proceed after identifying some resistors as being in series.

Discussion Status

Some participants have provided guidance on the configuration of the resistors, suggesting that certain resistors are in series and others in parallel. However, there is no explicit consensus on the final equivalent resistance, and the discussion remains open to further verification and exploration.

Contextual Notes

Participants are working with a specific circuit diagram that is not provided in the thread, which may lead to varying interpretations of the resistor arrangements. There is also mention of using Kirchhoff's law for verification, indicating a reliance on established principles to support their reasoning.

The Attempt at a Solution



I know the two 4 Ohm resistors (on the same wire) are in series and thus add to 8 Ohms. However, I do not know where to go from here. When the resistors are in a box, with one on each side, are they in series? Or are they two parallels?

Thanks!

I believe the 2,4,2 ohm resistors are all in series since the same current flows through them.

So this would leave me with two parallel resistors of 8 Ohms each? And finding the equivalent resistance would give us 4 Ohms?

If you (or someone else) can confirm this, it would be greatly appreciated!
 
yep. 8 ohm 8ohm are in parrellel giving 4 ohm net resistance. can be veryfied using kirhoff's law to show current in both branches are the same.
