Ohm’s law was founded by a man named George Ohm. He says that the relationship between voltage, current, and resistance of a conductor. This association is essential in creating electrical and electronic circuits to safeguard the voltages and currents in the components to stay within the specifications. The critical difference between Ohmic and Non-Ohmic conductors depends upon which adheres to Ohm’s law.

An example of an Ohmic conductor is the resistor. The voltage drops across a resistor to become Non-Ohmic, and the resistance would also increase. Even ordinary wires are considered as Ohmic conductors. Non-Ohmic conductors do not adhere to Ohm’s law, and they have distinct differences from Ohmic conductors.

Some examples of Non-Ohmic conductors include bulb filaments and semiconductors such as diodes and transistors. A diode gives a continuous voltage drop even if you change the current, so it does not follow Ohm’s law. The opposite occurs in a light bulb filament; even as you raise the voltage quite a bit, it only permits a certain amount of current to pass through. Incandescent light bulbs, for example, have been providing us with the light to read and eat our meals for over a century.

Ohmic conductors are conductors that obey Ohm’s law. The law states that the current passing through an electric circuit is directly proportional to the voltage applied. This shows that the relationship between the current and the voltage is linear. However, an Ohmic conductor can still be classified as a non-Ohmic conductor if it does not maintain the normal temperature range that has been set for it. For instance, if the current flowing through the circuit is directly proportional to the voltage applied, but there is an increase in the heat generated as the current flows, the conductor is considered a non-Ohmic conductor. Non-Ohmic Conductors, on the other hand, do not obey Ohm’s law. This is because the relationship between the current and the voltage is not linear. Examples of non-Ohmic conductors include; transistors, bulb filaments, diodes, etc. the fact that non-Ohmic conductors do not obey Ohm’s law does not make them bad conductors.

The ohmic conductor will have the tendency to have a linear relationship. This is between the voltage and the current. When you say non-Ohmic, this means that the relationship between the voltage and the current is not going to be linear. So another difference between the two is if they follow Ohm’s Law or not. When it comes to Ohmic devices, you can count on the resistance being constant but with non Ohmic devices, it is very likely that the resistance will not be constant. It will be up to you to choose the type of devices that you would need. One example of an Ohmic conductor is going to be a resistor because this will make sure that the current will always pass through.
