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.

Megohm

MΩ

Definition

A unit of electrical resistance equal to one million ohms (10^6 Ω). Used for measuring very high resistances in electrical insulation and high-voltage applications.

History/Origin

Part of the metric system with the mega- prefix, representing 10^6. Commonly used in electrical engineering for measuring insulation resistance and high-impedance circuits.

Current Use

Extensively used in electrical insulation testing, high-voltage equipment, and measuring very high resistances in electronic circuits and components.
