Limitation of ohm law

NettetOhm’s law establishes a link among voltage, current, as well as resistance. Yet, this is not required for all devices to adhere to Ohm’s theory. There are several non-ohmic gadgets. According to Ohm’s rule, current is exactly proportionate with voltage. This Law has several limits too. Ohm’s Law does not apply to nonmetallic wires.

What is Ohm

Nettet2. sep. 2024 · What is ohm’s law? Ohm’s law states that at a constant temperature, current ‘I’ through a conductor between two points is directly proportional to the potential difference or voltage ‘V’, across the two points. Thus, the ratio V : I is a constant. This constant is called as the resistance (R) of the conductor.
