Ohm’s Law - How Voltage, Current, and Resistance Relate

WebAug 15, 2024 · Ohm’s law in this form really defines resistance for certain materials. Ohm’s law (like Hooke’s law) is not universally valid. The many substances for which Ohm’s law holds are called ohmic. These include good conductors like copper and aluminum, and some poor conductors under certain circumstances. WebOhmic and Non-Ohmic Conductors Conductors which obey Ohm’s Law have a constant resistance when the voltage is varied across them or the current through them is increased. These conductors are called ohmic conductors. A graph of the current vs. the voltage across these conductors will be a straight-line. WebOhm’s Law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions, such as temperature, remain constant. phillips 66 fitch credit rating
