WebApr 11, 2024 · The SI unit of resistance is Ohm (Ω), named after Georg Ohm. If 1 A of current flows through the ends of a conductor when the two ends are kept at 1 V of potential difference, the resistance of the conductor is defined as 1 Ohm. 1 Ω = 1V/1A. In terms of fundamental units, Ohm can be expressed as, Ω = J S A 2.
