Limitations of Ohm's Law:
Ohm's law is not a fundamental law of nature. There are a number of commonly used circuit elements which do not obey this law called Non – Ohmic conductors.
Non – Ohmic conductors have one or more of the following properties:
1. Potential difference (V) depends on current (I) non-linearly.
2. The relation between V and I is non-unique, that is, for the same current I, there is more than one value of voltage V.
3. The relationship between V and I depends on the sign of V f or the same absolute value of V.
