Mar 5, 2023 · 安培（英语： ampere ，法语： ampère ）简称安（amp），是电流强度的单位，国际单位制七个基本单位之一 ，符号 A 。 安培是以 法国 数学 家和 物理 学家 安德烈-马里·安培 命名的，为了纪念他在 经典电磁学 方面的贡献。
The ampere (/ ˈ æ m p ɛər / AM-pair, US: / ˈ æ m p ɪər / AM-peer; symbol: A), often shortened to amp, is the unit of electric current in the International System of Units (SI). One ampere is equal to 1 coulomb (C) moving past a point per second.
The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 x 10 –19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of Δν Cs.
安培（英語： ampere ，法語： ampère ）簡稱安（amp），是電流強度的單位，國際單位制七個基本單位之一 ，符號 A 。安培是以法國 數學家和物理學家安德烈-馬里·安培命名的，為了紀念他在古典電磁學方面的貢獻。
Ampere, unit of electric current in the International System of Units (SI), named for 19th-century French physicist Andre-Marie Ampere. It represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt.
