WebJul 7, 2024 · Negative Resistances is a behavior in which the current and voltage are inversely proportional to each other. A normal circuit with a resistor following ohm’s law has a current drop, when the voltage decreases. In case of a negative resistance, the current increases with a voltage drop. WebLED bulbs do not obey Ohm's law. They are non-Ohmic devices. So, to quickly summarize what we learned, we found that if the voltage versus current graph for any material is a straight line passing through the origin, then that material obeys Ohm's law and we call such materials as Ohmic materials.
