Ohm’s Law Limitations. There are some limitations to Ohm’s law. They are as follows: Ohm’s law is an empirical law which is found true for maximum experiments but not for all. Some materials are non-ohmic under a weak electric field. Ohm’s law holds true only for a conductor at a constant temperature. Resistivity changes with temperature.
Ohm’s law is one of the most important topics for Class 10 and Class 12 students. So every science student in Classes 10 and 12 has read this article properly. While Ohm’s Law has its limitations, it remains an indispensable tool for basic circuit analysis and serves as a starting point for further exploration into the vast world of ...
Limitation of Ohm’s Law: $\left( 1 \right)$ Ohm’s Law is not applicable for unilateral electrical elements, for example diodes and transistors, as both of them allow the current to flow through in one direction only. While Ohm’s Law is applicable to those elements which allow current in both directions.
This is a topic of class 12 physics chapter 3: Current Electricity. In this resource, through our detailed notes on Ohm's law for class 12, we explore the definition, statement, and derivation of Ohm's Law, delve into the concept of electrical resistance and its dimensions, examine current-voltage relations, and discuss the limitations of Ohm's ...
Following are the limitations of Ohm’s Law:1. Ohm’s law is not applicable for unilateral electrical elements like diodes and transistors as they allow the current to flow through in one direction only.2. For non-linear electrical elements with parameters like capacitance, resistance etc the voltage and current won’t be constant with respect to time making it difficult to use Ohm’s law.
