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 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.
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:)
current doublesAnswerIt depends on whether the wire is ohmic or non-ohmic. If it is ohmic, then the current will also double. If, like tungsten, it is non-ohmic, then it depends.... because doubling the voltage will cause its resistance to increase.Ohmic materials obey Ohm's Law, whereas non-ohmic materials do not.
non ohmic devices are diodes, LED's, Thermistors, LDR(light dependent resistors, cells in series.
Diode is a non-ohmic conductor since in diodes current-voltage relation ship does't obey Ohm's law....the relationship between current and voltage is nonlinear here,...
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.
