Question

Example of non ohmic devices

Answer 1

Non-Ohmic conductors do not follow Ohms law and have their own characteristics. There are a number of examples of non-Ohmic conductors; including bulb filaments and semiconductors like diodes and transistors.

A diode provides a near constant voltage drop even if you vary the current, so it does not follow Ohm’s law. The opposite happens in a light bulb filament; even as you increase the voltage significantly, it only allows a certain amount of current to pass through.

Even if non-Ohmic conductors do not follow Ohm’s law, they have their own specialized uses that aid greatly in electrical and electronic circuits.

Incandescent light bulbs have been lighting our homes and semiconductors have made a lot of things possible.

Almost all electronic gadgets like phones, computers, even ordinary watches and remotes use semiconductors.

1.Ohmic conductors obey Ohm’s law while non-Ohmic conductors don’t

2.Resistors tend to be Ohmic at its designed operating temperature

3.Semiconductors and bulb filaments are non-Ohmic conductors
