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).

欧姆 (Ω) 是 电阻 的 SI 派生单位 ，以德国物理学家 Georg Simon Ohm 命名。尽管在早期的电报实践中开发了几个用于表示电阻的经验派生标准单位，但英国科学促进会早在早期就提出了一个从现有的质量、长度和时间单位派生出来的单位，并且尺寸适合于实际工作。

Ohm (Ω) Ohm (symbol Ω) is the electrical unit of resistance. The Ohm unit was named after George Simon Ohm. 1Ω = 1V / 1A = 1J ⋅ 1s / 1C 2. Table of resistance values of Ohm

Ohm is a unit of electrical resistance, named after Georg Simon Ohm, a German physicist who discovered Ohm’s Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature and other physical conditions remain constant.

歐姆 (Ω) 是 電阻 的 SI 派生單位 ，以德國物理學家 Georg Simon Ohm 命名。儘管在早期的電報實踐中開發了幾個用於表示電阻的經驗派生標准單位，但英國科學促進會早在早期就提出了一個從現有的質量、長度和時間單位派生出來的單位，並且尺寸適合於實際工作。

An ohm (referred to by the Greek letter Ω (Omega)) is the SI unit of resistance (R). It can be defined by Ohm's law and the equation: where is resistance in ohms, is voltage in volts, and the current in amperes. The ohm was named after Georg Ohm.

欧姆（或ohm ）是电阻的国际单位制 (SI) 单位。换句话说，欧姆是用来表示电阻值的电气单位。 欧姆的符号是大写希腊字母欧米茄 (Ω)。然而，有时也会使用缩写欧姆。

The ohm (Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm. Although several empirically derived standard units for expressing electrical resistance were developed in connection with early telegraphy practice, the British Association for the Advancement of Science proposed a unit derived from ...

2024年5月27日 · Ohm（奥姆）是电阻的国际单位制（SI）单位，符号为Ω。 它定义为在温度20°C时，通过1安培电流的导体所产生的电压为1伏特时的电阻。 欧姆定律是电路学中的一个基本定律，描述了在电压保持恒定时，电流
