What is the Equivalent Resistance in a Series Circuit?

Click For Summary

Homework Help Overview

The discussion revolves around finding the equivalent resistance in a series circuit involving multiple resistors. Participants are exploring the concepts of series and parallel connections in the context of electrical circuits.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to calculate the equivalent resistance using various resistor combinations but questions whether their method is correct. Other participants provide feedback on the connections between resistors and suggest clarifying the arrangement of the circuit.

Discussion Status

Participants are actively engaging with the problem, questioning the arrangement of resistors and discussing the implications of series and parallel connections. Some guidance has been offered regarding the connections, but there is no explicit consensus on the correct approach yet.

Contextual Notes

There are indications of confusion regarding the connections of resistors R1, R2, R3, and R4, and the need for visual aids to clarify the circuit setup has been mentioned.

Hi guys,I'm new here and maybe I'm posting this homework in a wrong part of the forum.I tried to find the equivalent resistance.It may be a simple homework but I am learning first for the electricy physic.I tried to find Re first R2+R3=4 Ω and than found Re=1/4 Ω + 1/2 Ω + 1/2 Ω can i slove it this way? (P.s sorry for my bad english.)

R1 is not parallel with the resultant of R2, R3, R4. Check.

Can it be formed so?

Then I did it so:R23=2Ω +2Ω =4Ω and 1/Re=1/4Ω + 1/2Ω +1/2Ω = 5/4Ω Re=4Ω /5? Is this the right way of slowing it?

No. What does parallel connection mean? Explain which resistors are connected in series and which are parallel.

R2,R3 are connected in series.And R4 R1 in paralel?

Yes.

No. The equivalent resistance of R2 and R3 is in parallel with R4. Do you see why?

Yes but i don't know how is it connected the R1,and how to find the eq reasistance of this circuit can u help me :/ .

Draw figures after each reduction. R2 and R3 are in series as you said. Replace them with a single resistor and draw the figure.
