What are ohmic and non-ohmic resistance?
|Ohmic Conductors||Non Ohmic Conductors|
|1. Conductors that obey Ohm’s Law are called Ohmic conductors.||1. Conductors which do not obey Ohm’s Law are called Non-Ohmic conductors.|
|2. In Ohmic conductors, current is proportional to voltage.||2. In Non-Ohmic conductors, current is not proportional to voltage.|
|3. Magnitude of current remains unchanged when current or voltage is reversed in Ohmic conductors.||3. Magnitude of current changeswhen current or voltage is reversed in Non-Ohmic conductors.|
|4. In Ohmic conductors, temperature affects current and resistance.||4. In Non-Ohmic conductors, different factors affect current and resistance.|
