Answer:
Such devices are termed non-linear and do not obey Ohm's law. Examples include filament lamps, diodes and thermistors. The resistance of a non ohmic device may vary with time. ... This leads to a higher frequency of collisions between electrons and ions; the resistance of the component has hence increased.
