WebReal wires are made from "ohmic" materials, meaning they have some amount of resistance and obey Ohm's law. If we want to account for this in a circuit diagram, how do we do so? We include additional resistors representing the resistance of the wire and then treat the wires in the diagram as "ideal wires." WebThe light bulb and the light emitting device do not produce a linear graph like the law says. What does not follow Ohm’s law? Non- Ohmic Conductors are conductors who don’t obey the law. Ohm’s law does not apply to semi conductors. Other examples include transistors, vacuum tubes, and triode valves. Non – Ohmic Circuits are the types of ...

WebOct 30, 2024 · 2. Ohm's Law is perhaps the poster-child for tautology. Components that obey Ohm's Law do, and those that don't, don't. Ohm's Law is a description of behaviour, that V and I are proportional. Almost no random material or component is going to follow it exactly, but many 'resistors' follow it approximately, and well enough to be called 'resistors'. http://complianceportal.american.edu/does-a-light-bulb-follow-ohms-law.php
