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 is an electrical unit of resistance. The Ohm symbol is Ω.

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.

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. Whether you're a …

Resistance is the property of a material that opposes the flow of electrical current, and is measured in ohms. The symbol for ohm is the Greek letter omega (Ω). Resistance is influenced by various …

May 27, 2025 · Named after the German physicist Georg Simon Ohm, this law is the bedrock principle that governs how current, voltage, and resistance interact in electrical circuits. It may seem basic, but …

Dec 3, 2025 · The quotient V / I for a given piece of material is called its resistance, R, measured in units named ohms. The resistance of materials for which Ohm’s law is valid does not change over …

Formed in 1969 by Robert W. Kirk, along with sons James, Joseph and William Kirk, OHM Corp. evolved into largest pure play environmental clean-up company in all of North America.

Jan 18, 2023 · The ohm is the standard unit of electrical resistance in the International System of Units (SI). It's one of the derived units defined in the SI standard, which means it's based directly or …

According to Ohm’s Law, resistance (ohms) equals voltage (volts) divided by current (amperes): R = V/I. This relationship is foundational in electrical engineering.
