Reducing Equivalent Resistors and Capacitors

Click For Summary

Homework Help Overview

The discussion revolves around reducing a circuit consisting of resistors and capacitors, where all resistors have a value of R and all capacitors have a value of C. The original poster attempts to simplify the circuit and seeks clarification on the configuration of the capacitors and resistors.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster describes their attempts to reduce the circuit by identifying series and parallel configurations of capacitors and resistors. They question whether certain capacitors are in parallel and seek confirmation on their understanding of circuit connections.

Discussion Status

Participants are actively engaging with the original poster's attempts. Some provide clarifications on the definitions of series and parallel connections, while others express uncertainty about the extent of the circuit's reduction. There is an ongoing exploration of possible simplifications.

Contextual Notes

There are references to images that illustrate the circuit, which are not accessible to all participants. The original poster also expresses a desire for further simplification, indicating a potential lack of clarity in the current configuration.

Homework Statement



Reduce the circuit as much as possible. All resistors have R and all capacitors have same C.

Homework Equations





The Attempt at a Solution

And this is my reduced one (I only reduced two capacitors in series and two parallel resistors)

The reduced capacitors (the ones in the right corner of that little square) =

1/C_eq = 1/C + 1/C = 2/C
C_eq = .5C

1/R_eq = 1/R + 1/R = 2/R
R_eq = .5R


(Ignore the random squiggly at the bottom)

Anyway - that's as far as I got. I'm not sure if the two capacitors in the center are considered parallel? And if so, is that other capacitor on the far left considered in parallel with them too? (even though there are resistors between them?)

Can you attach the images to your post? I really don't feel like joining facebook just to look at your problem. :smile:
 
oh, sorry - they were supposed to show up!
 
Yeah, the two caps in the middle are in parallel, but the other one you are asking about would not be. Think of parallel as whether or not the wires are connected at both ends. Think of series as whether or not two elements share a common connection. (A fancy name for connection is a node.)
 
Is this as far as it can be reduced?

Hmm...is this it? It seems like something simpler could be achieved somehow...*sigh*

Hello,
Can anyone give me a hint how to calculate the impedance of the following circle ?
Thank you
