abohm

Thân thiện

A technician measures a tiny resistor with an abohm meter.

Definition

Noun: - A unit of electrical resistance: An abohm is a unit of resistance in the centimeter-gram-second (CGS) electromagnetic system of units. It is defined as one billionth (10⁻⁹) of an ohm, the standard SI unit of electrical resistance.

Usage

The term "abohm" is a technical, scientific term used primarily in physics and electrical engineering contexts, especially when discussing historical or theoretical measurements within the CGS system. - The resistance was measured in abohms due to the experimental setup using CGS units. - One abohm is an extremely small unit of resistance, equivalent to 0.000000001 ohms.

Advanced Usage

• The "abohm" is part of a family of CGS electromagnetic units prefixed with "ab-" (from "absolute"). Other related units include the abampere and the abvolt.
• It is largely obsolete in practical applications, having been superseded by the International System of Units (SI), where the ohm is the standard unit.

Variants and Related Words

• Ohm (n): The SI unit of electrical resistance, defined as the resistance between two points of a conductor when a constant potential difference of one volt produces a current of one ampere.
• Abampere (n): The CGS electromagnetic unit of electric current.
• Abvolt (n): The CGS electromagnetic unit of electromotive force (voltage).

Synonyms

• Nanohm (n): A modern term meaning one billionth of an ohm (1 nΩ = 10⁻⁹ Ω). While numerically equivalent, "nanohm" is an SI-compatible unit, whereas "abohm" is specific to the CGS system.
