Also known as Ω
The ohm (symbol: Ω, the uppercase Greek letter omega) is the unit of electrical resistance in the International System of Units (SI). It is named after German physicist Georg Ohm (1789–1854). Various empirically derived standard units for electrical resistance were developed in connection with early telegraphy practice, and the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time, and of a convenient scale for practical work as early as 1861.
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.
