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.

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

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 …

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. …

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 …

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 …

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

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points, with the proportionality constant being defined as the …

What is Ohms? Ohms (Ω) are the unit of measurement for electrical resistance, defining how much a material or circuit opposes the flow of electric current. Named after Georg Simon Ohm, …
