Homework Help Overview

The discussion revolves around a circuit analysis problem involving capacitors arranged in both series and parallel configurations. Participants are attempting to calculate the voltages and charges on each capacitor based on their connections.

Discussion Character

  • Exploratory, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to clarify the arrangement of capacitors, questioning whether certain capacitors are in parallel or series. Other participants suggest a systematic approach to identifying equivalent connections and re-evaluating the circuit configuration.

Discussion Status

The discussion is progressing with participants exploring different interpretations of the circuit layout. Some guidance has been offered regarding the relationships between the capacitors, but there is no explicit consensus on the final arrangement yet.

Contextual Notes

Participants are working with a visual representation of the circuit, and there may be some ambiguity in the connections that is affecting their understanding. The original poster expresses uncertainty about the configuration, indicating a need for clarification.

Ok this should be an easy one. I am trying to calculate voltages and charges on each capaciter. But first I want to make sure I understand the picture correctly, because soemthing isn't matching

c1 and c5 are parallell to each other. c3 and c4 are parallel to each other. then c15, c2, and c34 are in series with each other?
please correct me if I'm wrong. thanks

What you need to do is systematically replace unambiguous examples of parallel or series connections with their equivalent, then reexamine the circuit and do it again, repeating the process until done.

For example, c1 and c5 are not really in parallel, since the other capacitors are connected between them. But C3 and c4 are definitely in series, since they are directly connected. Start there.
 
o wait a minute. so C3 and c4 are in series. then c34 is parallel to c2. then c1 is in series with c234 which is in series with c 5
ok I am gunna try this out and see if i get the right answer, thanks
 
Now you're cooking. :wink:
