Click For Summary

Discussion Overview

The discussion revolves around a homework problem involving a circuit network (referred to as "network N") that includes resistors, voltage sources, and current sources. Participants are exploring how to determine the voltage as a function of current (V(I)) based on experimental measurements taken with ideal sources.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant describes the homework problem and the experimental setup involving an ideal current source and an ideal voltage source.
  • Another participant suggests using Thevenin and Norton equivalent circuits to approach the problem.
  • A follow-up response clarifies that V(I) refers to the voltage between specific points (a, b) in the circuit.
  • Further questions are posed regarding the identification of the Thevenin and Norton equivalents and the specific current to consider for measuring V(I).

Areas of Agreement / Disagreement

Participants appear to agree on the need to use Thevenin and Norton equivalents, but there is uncertainty regarding the specifics of what V(I) represents and how to proceed with the calculations. The discussion remains unresolved.

Contextual Notes

There are limitations in the clarity of what V(I) specifically represents, as well as ambiguity regarding the current to be used in the calculations. The discussion does not resolve these aspects.

Who May Find This Useful

Students working on circuit analysis problems, particularly those involving Thevenin and Norton equivalents, may find this discussion relevant.

Homework Statement


I have "network N" that includes (resistorse, voltage and current sources), and we do 2 experiments:
1. connecting idial current source, and measuring 3V
2. connecting idial voltage source, and measuring 5A.

need to find V(I)=?

The Attempt at a Solution


Nothing much...

Can someone give me a hint, please?

Thanks.

You are expected to use the Thevenin and Norton equivalent circuits perhaps?

What is V(I) supposed to represent?
 
Yes, i am expected to use them...
V(I) for points a,b.
 
Well... ? Have you found the Thevenin and/or Norton equivalents for the black box?

I figured that you'd want to measure Vba but you presumably want the curve or equation for the Vba as a function of current. But what current? The current in the circuit OK but which circuit? Can you tell me in words what V(I) represents?

I'm not asking these questions for information: those are hints.
