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.

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? )
Thanks though!
