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. WebAug 9, 2024 · The SI unit of electrical current is the ampere, defined as 1 coulomb/second.

"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. " - Bitesize ohm's law
