what are ohmic and non ohmic conductors

Question

Answer

The conductors which obey ohms law are ohmic conductor. And totally opposite is non ohmic conductor

Answer

Ohmic conductor- which follows the ohm's law.ex all metals.non ohmic conductor-which does not follow the ohm's law.ex plastic,wood.

Answer

Ohmic and Non-Ohmic Conductors

Ohmic and non-ohmic conductors are terms used to describe the behavior of different materials when an electric current is passed through them. These terms help us understand how different types of materials respond to an applied electric field and the relationship between current and voltage.

Ohmic Conductors

Ohmic conductors, also known as linear conductors or ohmic materials, are materials that exhibit a linear relationship between the current passing through them and the voltage applied across them. In other words, the current is directly proportional to the voltage. The resistance of an ohmic conductor remains constant regardless of the voltage or current.

Characteristics of Ohmic Conductors:
- Linear relationship between current and voltage
- Resistance remains constant
- Follow Ohm's law: V = IR, where V is voltage, I is current, and R is resistance

Examples of ohmic conductors include most metals like copper, silver, and aluminum. These materials have free electrons that can move easily, leading to a linear relationship between the current and voltage.

Non-Ohmic Conductors

Non-ohmic conductors, also known as non-linear conductors or non-ohmic materials, do not follow Ohm's law. The relationship between the current and voltage is not linear, and the resistance of these materials varies with the applied voltage or current.

Characteristics of Non-Ohmic Conductors:
- Non-linear relationship between current and voltage
- Resistance varies with the voltage or current
- Do not follow Ohm's law

Examples of non-ohmic conductors include semiconductors like silicon and germanium, as well as some gases like neon and mercury vapor. These materials have a more complex behavior due to factors such as temperature, doping, or the presence of impurities. The resistance of non-ohmic conductors can increase or decrease with the applied voltage or current, making their behavior more intricate compared to ohmic conductors.

Conclusion

In summary, ohmic conductors exhibit a linear relationship between current and voltage, and their resistance remains constant. On the other hand, non-ohmic conductors do not follow Ohm's law, and their resistance varies with the applied voltage or current. Understanding the behavior of these different types of conductors is crucial in various applications of electrical circuits and can help in designing and analyzing electrical systems efficiently.
