If the temperature changes (often due to large current e.g filament lamp). In the statement of Ohm's Law, it says it applies only to a metal conductor at constant temperature. So a non-metal conductor-e.g. semiconductor, including diode, LED, thermistor, and an electrolyte don't obey Ohm's Law as a matter of course.
