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

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:
