Need help w/ circuit analysis

Click For Summary

Discussion Overview

The discussion revolves around a circuit analysis problem, specifically using mesh analysis to determine the power delivered by a current-controlled voltage source. Participants are addressing the application of Kirchhoff's Voltage Law (KVL) in the context of the provided circuit diagram.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests urgent help with circuit analysis using mesh analysis.
  • Another participant emphasizes the need for the original poster to show their own work to facilitate assistance, referencing a previous post where this was also requested.
  • A participant proposes a KVL equation but expresses uncertainty about the next steps in the analysis.
  • Concerns are raised regarding the accuracy of the KVL equations, specifically that the currents labeled as Ix are not all the same due to their paths through the circuit.
  • Clarification is provided that all resistors in the circuit are in ohms.

Areas of Agreement / Disagreement

Participants do not appear to reach consensus on the correctness of the KVL equations or the identification of currents in the circuit. There is an ongoing debate about the application of mesh analysis and the need for the original poster to provide more information.

Contextual Notes

There are unresolved questions regarding the definitions of currents in the circuit and the specific values of the resistors. The discussion also highlights the importance of showing work in problem-solving.

Who May Find This Useful

Students or individuals seeking assistance with circuit analysis, particularly those interested in mesh analysis and KVL applications.

Xtasy, you need to show some of your own work in order for us to help you . That's a rule here on the PF. As in your first post on the PF:

https://www.physicsforums.com/showthread.php?t=153893

you were prodded to provide your own start to the problem. Show us what you know about mesh analysis here so far, and how it applies to this problem in your attachment. Then we'd be happy to provide some hints and tips.
 
Well, I could take KVL around the loop -Vx/8 + 6Ix + 6Ix - 1Ix=0 KVl around the lower right hand +32Ix -15Ix -1Ix= 0 = 16Ix=0. Then what?
 
The currents in your KVL equations are NOT all Ix. Ix is the current through that bottom right resister and will not be the same once it passes through that first node. Also what are the units for the resisters, kohm or ohm?
