Homework Help Overview

The discussion revolves around analyzing impedances in a five-element circuit, specifically focusing on a part of a homework problem labeled as 18b. Participants are exploring relationships between various impedances and currents in the circuit.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss potential symmetry in the circuit, suggesting that Z1 may equal Z2 and Z3 may equal Z4. There are questions about the implications of these assumptions on the current I5. Some participants express uncertainty about making assumptions without explicit statements in the problem.

Discussion Status

The discussion is ongoing, with participants sharing links to images and external resources for clarity. There is a mix of interpretations regarding the equality of impedances, and some participants are seeking clarification on specific steps in the problem-solving process.

Contextual Notes

Participants note that assumptions about symmetry may not be explicitly stated in the problem, leading to questions about the validity of those assumptions. There is also mention of using loop current methods and current equalities in their approaches.

Just help me with 18 b.

Homework Equations


V1 = c1I1Z1. Same for V2,3,45. V = V1+V2+V3+V4+V5. V/I=Z=impedance.

The Attempt at a Solution


Maybe because of symmetry Z1=Z2 & Z3=Z4. Perhaps Z5 takes out one of the branches? Can I get a hint?

Trying to read your image gives me eyestrain, but if Z1=Z2 & Z3=Z4 then what is I5 ?

I would not assume anything is equal to another unless the problem explicitly says that

I am following up on what YOU said not what the problem statement said

One more thing: I still don't know how they jumped from the 2nd to last line to the last line in this problem (in the answer I mean).
