Ohm

Definition

The ohm is the SI derived unit of electrical resistance, impedance, and reactance. It is defined as the resistance between two points of a conductor when a constant potential difference of one volt produces a current of one ampere.

History/Origin

Named after German physicist Georg Simon Ohm (1789-1854), who formulated Ohm's law. The ohm was officially adopted as the unit of electrical resistance in 1881 at the International Congress of Electricians.

Current Use

Widely used in electrical engineering, electronics, and physics. Essential for measuring resistance in circuits, components, and electrical systems. Standard unit in all electrical calculations and measurements.

Quantized Hall Resistance

Rₖ

Definition

A fundamental constant of nature equal to h/e² ≈ 25,812.8056 ohms, where h is the Planck constant and e is the elementary charge. Used in the quantum Hall effect.

History/Origin

Discovered in the quantum Hall effect by Klaus von Klitzing in 1980. This resistance value is a fundamental constant that appears in quantum mechanics and is used for precision resistance standards.

Current Use

Used as a precision resistance standard in metrology and quantum physics. Essential for high-precision electrical measurements and quantum resistance standards.
