Homework Help: Give an example of an ohmic and non-ohmic device

  1. Feb 26, 2007 #1
    1. The problem statement, all variables and given/known data

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

    2. Relevant equations

    N/A

    3. 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

    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:
