【醫(yī)】 potential

1. 電路中的一個(gè)參考點(diǎn)，該點(diǎn)電位作為標(biāo)稱的零電位，其它所有電位均相對(duì)于該點(diǎn)而定。經(jīng)常，但并非總是，將該點(diǎn)直接連接到地。作為動(dòng)詞，指連接到地線上的過(guò)程，也稱作接地。
   A point considered to be at nominal zero potential and to which all other potentials in the circuit are referred, often, but not always, connected to the actual surface of the earth; as a verb to connect to a ground. Also called earth.
2. 電（子）之所以流動(dòng)，是因?yàn)?/a>干電池上正負(fù)兩端上的電的狀況有差別所致，對(duì)于這種差別，我們稱之為“電位差”。
   The difference in the electrical condition of the terminals "+" and "-" of the dry cell which tends to make electricity flow we describe as a difference of electrical potential.
3. 歐姆電阻單位，一段導(dǎo)體兩端的電位差為伏特時(shí)產(chǎn)生一安培電流，那么這段導(dǎo)體的電阻就等于歐姆
   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.
