Homework Help Overview

The discussion revolves around a circuit problem involving a triangle configuration and the application of a voltage source across specific nodes. Participants are examining the correctness of a drawn diagram related to question 26.5, specifically focusing on the placement of voltage sources and connections between components.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to clarify the configuration of the circuit after applying a voltage across certain points and seeks validation of their drawing. Other participants question the labeling of nodes and the appropriate connections for components, such as the 20-ohm resistor.

Discussion Status

The discussion is actively exploring the correct configuration of the circuit. Some participants have provided guidance on where to place the voltage source, indicating a productive direction. However, there is no explicit consensus on the final configuration yet.

Contextual Notes

Participants are working within the constraints of the problem instructions, which specify the placement of the voltage source. There may be ambiguity regarding the labeling of nodes and the connections of components that are still under discussion.

I am not sure how the configuration would look like if we add a voltage across these points. I have drawn out what I think it would look like after a potential is applied across Vab. My question is, is this drawing correct?? What about Vbc and Vac?

This is question 26.5.

And here is my attempt for (a)

Once I figure out the configuration, I can easily add up the R_eq and find the I from that. But I need to make sure my configuration is correct!

For a diagram for part (a), the voltage source should be drawn between nodes a and b. You've not labeled node a correctly in the second diagram.
 
What should the 20ohm be connected to?
 
If the instructions say to put the voltage source between nodes a and b, then that's where you connect it!
