Question
What are non-ohmic conductors? Give one exmaple. Draw a current-voltage graph for a non-ohmic conductor.

Solution
The conductors which do not obey Ohm’s law (i.e., V/I is not constant) are called non-ohmic conductors.
Example: Diode valve.
The current-voltage graph for a non-ohmic conductor is shown in figure alongside.
