Resistance unit breakdown
WebJun 17, 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. Webohm: The ohm is the standard unit of electrical resistance in the International System of Units ( SI ). Ohms are also used, when multiplied by imaginary numbers, to denote reactance in alternating-current ( AC ) and radio-frequency ( RF ) applications. Reduced to base SI units, one ohm is the equivalent of one kilogram meter squared per second ...
