When is ohm’s law not applicable? – Quora

With all this talk of suspending laws and enacting Enabling Acts, did you know one of the fundamental laws of electricity - Ohm's Law often suspended for broad areas. Diodes, which include solar panels and LED lighting for example often violate ohm's law.

Ohm's law is basically not a fundamental law which means it has exceptions.

Ohm's law is an empirical law which means it is stated based on some observations.Though it works most of the time there are indeed cases where ohm's law do not satisfactorily explain certain phenomena. One example is an incandescent light bulb. The tungsten filament in the bulb does not follow Ohm's law. As the voltage in the wire filament increases it heats up. The resistance of a wire changes as its temperature changes. Hence the graph of the current and voltage in the wire will curve. The light bulb filament violates Ohm's law.

Often if extreme currents are applied to wires, they heat up, change their resistances, and violate Ohm's law. There exist many conductors in nature which do not obey ohm's law.They are known as non-ohmic conductors.For such conductors,the graph between potential difference and currentis not a straight line passing through origin.

Vacuum tubes, semiconductors, transistors, liquid electrolytes, thermistors, etc are examples of non ohmic conductors.Circuits which consist of these non ohmic conductors are called non ohmic circuits or non linear circuits.
