A 'non-ohmic' conductor is one that does not obey Ohm's Law -i.e. the ratio of voltage to current is not constant when the voltage across it varies.
ohmic ocnductor is a material which obeys ohm's law: i.e. the voltage and current are directly proportional 2 each other anda non-ohmic ocnductor is a material which doesn't obey ohm's law:)
no.....thermistors are not ohmic.
which law follow non ohmic substances

ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
A common example of a non-ohmic material is a light bulb filament. As the temperature of the filament increases, the resistance also increases, meaning it does not follow Ohm's Law (V = IR) consistently. This non-linearity is due to the change in resistance with temperature.
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
Vacuum tubes are non-ohmic devices because their resistance changes with voltage and current. This non-linearity in resistance is due to the nature of the electron flow within the vacuum tube, causing it to exhibit non-ohmic behavior.

An 'ohmic' resistor is one which obeys Ohm's Law. For Ohm's Law to apply, the resistance of a circuit must be constant over the range of incremental voltages applied to it. If the resistance changes over an incremental range of voltages, then it is said to be 'non-ohmic', and it does not obey Ohm's Law.
A filament lamp is a non-ohmic conductor because its resistance changes with applied voltage. As the voltage increases, the resistance also increases. This is due to the temperature-dependent behavior of the filament material, which causes the resistance to vary.
