Marie Ampère (1775-1836); thecoulomb, after the French scientist Charles A. de Coulomb (1736-1806); thefarad and the faraday, after the British scientist Michael Faraday (1791-1867); thejoule, after the British scientist James P. Joule (1818-1889); thenewton, after the British scientist Sir Isaac Newton (1642-1727); theohm, after the German scientist Georg S. Ohm (1789-1854); thevolt, after the Italian scientist Count Alessandro Volta (1745-1827); and thewatt, after the British scientist James Watt (1736-1819). Definitions such as that ofohm, "a unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals,” take on more human connotations when we think of how human contributions to the study of electricity are memorialized in them.The dates of first recorded use of the terms in English are as follows:ampere, 1881; coulomb, 1881; farad, 1861; faraday, 1904; joule, 1882; newton, 1904; ohm, 1870 (suggested in 1861); volt, 1873; and watt, 1882. 有人可能会问经过了多少位欧洲科学家才点亮了灯泡。如果我们以国际单位制或米—千克—秒单位制中各种单位之名称的形式来考虑的话，相当数量的人被包括了。这些单位按字母顺序排列是安培， 以法国科学家安德烈·马里耶·安培(1775—1836年）命名； 库仑， 以法国科学家夏尔·埃·德库仑(1736-1806年）命名； 法拉 和 法拉第， 以英国科学家迈克尔·法拉第(1791—1867年）命名； 焦耳 以英国科学家詹姆斯·皮·焦耳(1818—1889年）命名； 牛顿， 以英国科学家伊萨克·牛顿爵士(1642—1727年）命名； 欧姆， 以德国科学家格奥尔格·斯·欧姆(1789—1854年）命名； 伏特， 以意大利科学家亚历山德罗·沃尔塔伯爵(1745—1827年）命名； 瓦特， 以英国科学家詹姆士·瓦特(1736—1819年）命名。 定义诸如欧姆， “电阻单位，等于一伏特电压加于导体两端在导体内部产生一安培电流之导体电阻”， 当我们想到人们对电学做出的贡献是怎样在这之中得到纪念的时候，就带上了更多的人文内涵。英语中首次有记录的使用这些说法的时间如下：安培， 1881； 库仑， 1881； 法拉， 1861； 法拉第， 1904； 焦耳， 1882； 牛顿， 1904； 欧姆， 1870（在1861年建议使用）； 伏特， 1873；和 瓦特， 1882 〔ohmmeter〕An instrument for direct measurement in ohms of the resistance of a conductor in ohms.欧姆：以欧姆为单位来对导体电阻进行直接测量的仪器〔vibrator〕An electrical device consisting basically of a vibrating conductor interrupting a current.振动器：主要包含一种能打断电流的振动导体的电动设备〔metal〕Abbr.
