Question

Differences between ohmic and non ohmic conductors

Answer 1

• Conductors that obey Ohm’s Law are called Ohmic conductors while those that do not obey Ohm’s Law are called non Ohmic conductors.

• Magnitude of current remains unchanged when current or voltage is reversed in Ohmic conductors; the magnitude changes in the case of non Ohmic conductors.

• In Ohmic conductors, current is proportional to voltage whereas this is not the case with non Ohmic conductors

• In Ohmic conductors, temperature affects current and resistance whereas in non Ohmic conductors, different factors affect current and resistance.
