ohm

Also known as Ω

SI-enhet för elektrisk resistans

AI overview

An ohm is the standard unit used to measure electrical resistance, which is the opposition that a material presents to the flow of electric current. It matters because it provides a common way to quantify and compare how much different materials and components resist electricity, making it essential for designing and understanding electrical systems.

Ohm (betecknas med Ω) är SI-enheten för resistans, reaktans och impedans. 1 ohm är den resistans som vid 1 volt släpper igenom laddningsmängden 1 coulomb per sekund, det vill säga 1 ampere. 1 Ω = 1 V/A. Enheten är uppkallad efter Georg Ohm som formulerade Ohms lag.
