Question

V i characteristics of ohmic and non ohmic conductors

Answer 1

Answer:

The main difference between an Ohmic and a non-Ohmic conductor is whether they follow Ohm's law. An Ohmic conductor would have a linear relationship between the current and the voltage. With non-Ohmic conductors, the relationship is not linear. A good example of an Ohmic conductor is the resistor.

Answer 2

Ohmic conductors follows ohm's law and non- ohmic conductors does not follow ohm's law  

Explanation:

Ohmic conductors :-

• Conductors that follows ohm's law are known as ohmic conductors. According to ohm's law when some potential difference is applied to any conductor then current flows through that conductor is directly proportional to the potential when temperature and pressure are kept constant V∝ I and the proportional constant is the resistance of that conductor, resistor is a good example of ohmic device. Graph is linear in ohmic devices

Non- Ohmic conductors :-

• Conductors that does not follow the ohm's law are known as non-ohmic conductors. These conductors does not follow the direct relation of electric potential and current flowing through the conductor and the graph variation is non linear. Examples of non ohmic device is p-n junction diode, transistors, vacuum tubes etc
