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).

ohm, abbreviation Ω, unit of electrical resistance in the metre-kilogram-second system, named in honour of the 19th-century German physicist Georg Simon Ohm.

The symbol for ohm is the Greek letter omega (Ω). Resistance is influenced by various factors, including the type of material, its temperature, and its dimensions.

Ohm’s Law is a fundamental principle in electronics and electrical engineering. It defines the relationship between three essential electrical quantities: voltage, current, and resistance.
