What Are These Two Equations for Equivalent Capacitor Circuits?

Click For Summary

Discussion Overview

The discussion revolves around two equations related to equivalent capacitor circuits, specifically V[eq] = V[in] and R[eq] = -(V[oc] / I[oc]). Participants express confusion regarding these equations and their application within a specific circuit context.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Homework-related

Main Points Raised

  • Some participants express confusion about the meaning and application of the equations V[eq] = V[in] and R[eq] = -(V[oc] / I[oc]).
  • There are requests for clarification on how these equations relate to a specific circuit, indicating a need for visual context.
  • One participant suggests that the textbook may contain errors, contributing to the confusion.
  • Another participant recommends a specific textbook, "Introduction to Circuit Analysis" by Boylestad and Nashelsky, as a resource for understanding equivalent circuits.
  • Participants discuss the availability of resources, with one asking for links to free or affordable materials due to financial constraints.
  • There is a mention of a desire to learn electrical engineering and related fields, with participants sharing their learning experiences and aspirations.

Areas of Agreement / Disagreement

Participants generally agree on the confusion surrounding the equations and the need for clarification. However, there is no consensus on the correctness of the equations or the reliability of the textbook mentioned.

Contextual Notes

Participants highlight the lack of defined outputs in the context of the equations, which may contribute to the confusion. There is also an acknowledgment of potential errors in the textbook referenced.

Who May Find This Useful

This discussion may be useful for students studying electrical engineering or circuit analysis, particularly those seeking clarification on equivalent circuits and related equations.

I do not understand these two equations V[eq][/SUB] = V[in][/SUB] and R[eq][/SUB] = -(V[oc][/SUB] / I[oc][/SUB] )

Your help is much appreciated

Not sure what text method you are using but whatever it is, it is showing up for me as WAY too many characters.
 
Hmm, that's really strange that that happened, What it was suppose to say is that the equivalent voltage = voltage in, and equivalent resistance = -(voltage open circuit / Amperage open circuit)

You'll still need to show a specific circuit for that to make any sense to me.

This is exactly what they had, which is what confused me, cause their was no defined output

Well, I'm confused too. I can't see how the statements apply to that circuit.

ok, imma then assume that the textbook just had an error, because they have a lot of them. Thanks for your time
 
It's me again, check out introduction to circuit analysis from Boylestad and Nashelsky. Equivalent capacitor, inductor and resistor circuits are covered In that book in a very Clear way.

is their any way you can supply a link to a pdf of the book, or some sort of text, because I do not have much money at all, I am living in the struggle right now.

It loaded, but are you sure this is a very good resource, have you read it yourself, because its a little over 100 pages on capacitors and inductors, which is a pretty large chunk of time, I just want to make sure

Puglife, are you learning on your own?

yea, that most of the reason I joined physics forums, cause I don't really have anyone else to ask.

Your aim is electrical engineering?
 
  • #17
Thats what I would like to start out with, I will always be trying to learn more in life, and however long this takes me to learn ee, will allow me to gauge how long it will take me to learn more, like nuclear science, or programming.

Very Nice, well then, as you get further in your learning you can check out the other books from Boylestad, all of them refer to electronics, they are very well explained.
