Ohm Meaning and Definition

Pronunciation

Ohm /ˈoʊm/

Part of Speech

Noun (unit of electrical resistance)

Definition

A unit of electrical resistance in the International System of Units (SI), defined as the resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the seat of any electromotive force.

Examples

An ohm is the unit of measurement for electrical resistance.
The circuit requires 100 ohms to operate efficiently.

Synonyms

Ohm (symbol: Ω)
Siemens (reciprocal unit of electrical resistance)

Antonyms

Short Circuit (a direct path with zero or very low resistance)
Open Circuit (a break in the circuit with infinite or very high resistance)

Etymology

The unit of ohm was named after the German physicist Georg Simon Ohm, who was the first to express the relationship between electrical resistance, current, and voltage.

Usage Notes

Use the term “ohm” when referring to the unit of electrical resistance. In context, specify the circuit or electronic component to avoid confusion.

General usage: “The device requires 20 ohms for proper operation.”
Circuit-specific usage: “The speaker cables have 10 ohms of impedance.”

Cultural References

The term “ohm” has appeared in several science fiction works, including the novel “Ender’s Game” by Orson Scott Card, where it is mentioned in reference to electronic combat scenarios.
