WebNov 12, 2024 · There are also devices like tunnel diodes that have negative differential resistance ( d V d I) for some voltage and current range. If you want to know if it is possible to buy a resistor as a discrete component with a value that isn't a whole number, the answer is yes. It's entirely common to buy such things. 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.
