Homework Help Overview

The discussion revolves around identifying examples of ohmic and non-ohmic devices, specifically focusing on resistors and light-emitting diodes (LEDs). Participants are exploring the definitions and characteristics that differentiate these types of devices.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants seek to clarify the differences between ohmic and non-ohmic devices, referencing Ohm's law and the linearity of ohmic devices compared to the non-linearity of non-ohmic devices.

Discussion Status

There is a mix of confirmation and exploration of concepts, with some participants expressing a desire for validation of their examples while others engage in deeper questioning about the definitions and implications of ohmic versus non-ohmic behavior.

Contextual Notes

Participants mention the challenge of obtaining confirmation for their understanding, indicating a potential lack of clarity in the original question or context. There is also a reference to ongoing work related to diode behavior in circuits.

Homework Statement



Give an example of an ohmic and non-ohmic device.

Homework Equations



N/A

The Attempt at a Solution



Resistors - Ohmic device
Light Emitted Diode (LED) - Non-Ohmic device

I just need confirmation at the moment.
I am trying to answer some questions and this is all I have at the moment.
Thank you!

Well, I hate to just say yes or no. What is the difference between an ohmic and non-ohmic device?

ohm's law - linear...directly proportional between electric field and current density. (so ohmic...)

non linear and doesn't obey ohm's law = non-ohmic
 
Fine then...yes those are examples.:biggrin:

Thank you!
I asked quite few questions so far in this forum but so hard to get confirmation!

Currently, working on diode's behavior in a circuit...
 
Well, we don't like to just give answers out here. I hope I didnt cross that line.

Well, the book kind of states indirectly so I just needed confirmation. (Or is it the question that's asking me indirectly? :confused: )
Thanks though! :biggrin:
