What is an ohmic conductor?
ohmic conductors are those which obey ohm's law
Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
Differentiate between ohmic and non ohmic substances?
which law follow non ohmic substances
Is ohm law true for all conductors?
No. It only applies to a very limited range of conductors that are classified as being 'linear' or 'ohmic'. Most materials are 'non-linear' or 'non-ohmic', and these do NOT obey Ohm's Law. Non-linear conductors include tungsten and non-linear devices include diodes. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage; if it doesn't, then Ohm's Law doesn't apply. Period!

What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
Is vacuum tube ohmic or non-ohmic and why?
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.
Why is a thermistor a non ohmic conductor?
Ohm's law states that the current and potential difference (voltage) are directly proportional, provided the temperature is constant. The resistance of a thermistor is dependant on the temperature, so it does not obey Ohm's law. Components that do not obey Ohm's law are non-ohmic conductors.
Why are semiconductors referred to as being non-ohmic?
They do not follow the linear Ohm's Law equation relating current flow and voltage, like normal conductors do.
Example of non -ohmic and ohmic materials?
iron,gold
What is the necessary condition for a conductor to obey ohm's law?
No. In fact, most conductors don't obey Ohm's Law.For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage. For many conductors this simply doesn't happen and, for that reason, we call such conductors 'non-linear' or 'non-ohmic'.
