State Ohm's law?Is this law obeyed by all types of conductors?five example to support your answer.
Answers
Explanation:
Ohm's law, description of the relationship between current, voltage, and resistance. The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage,
the materials.
Not all conductors obey Ohm's law. ... Ohm's law is only true for resistors whose resistance does not depend on the applied voltage, which are called ohmic devices. ... With non-ohmic conductors, resistance depends on voltage and is no longer a constant.
The conductors which does not obey ohm's law is called Non – Ohmic Conductors. Semi – conductors like Germanium and silicon do not obey Ohm's law. Other examples include transistor, vacuum tubes, diode and triode valve. The circuits which consists of non - ohmic conductors are known as Non – Ohmic Circuits
