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 for a conductor at a constant temperature, the current through it is proportional to the potential difference across it Constant temperature implies constant resistance This is shown the equation below: Ohm’s law

WebOhm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Ohm’s Law Formula Voltage= Current× Resistance V= I×R V= voltage, I= current … WebGeorg Simon Ohm was a German physicist, best known for his "Ohm's Law", which states that the current flow through a conductor is directly proportional to the potential difference (voltage) and inversely proportional to the resistance. The physical unit of electrical resistance, the Ohm (symbol: Ω), was named after him.
