A volt is the unit we use to measure electrical pressure — how hard electricity is being pushed along a wire. If you think of electricity as water in a pipe, volts are the water pressure, while amps measure how much is actually flowing.

A volt是 the unit we use to measure electrical pressure我們用來測量電壓的單位 — how hard electricity is being pushed along a wire也就是電被沿著電線推得多用力. If如果 you think of electricity as water in a pipe你把電想成水管裡的水, volts volts就是 the water pressure水壓, while而 amps measure how much is actually flowingamps測量的是實際流過去的量

The higher the voltage, the harder the push, which is why a 220-volt wall socket is dangerous and a 1.5-volt battery in a remote control is not.

The higher the voltage電壓越高, the harder the push推力就越強, which is why這就是為什麼 a 220-volt wall socket is dangerous220伏特的牆壁插座很危險 and而 a 1.5-volt battery in a remote control is not遙控器裡1.5伏特的電池不會

You meet the word mainly as a number plus the unit: a 9-volt battery, 110 volts, a 5-volt charger. Written short it is V with a capital letter and no dot — 12V, 240 V — and by convention the unit name is lower-case (volt) even though the letter symbol is capital, because it honours a person.

You meet the word mainly as a number plus the unit你會遇到的這個字大多是數字加單位的形式: a 9-volt battery像a 9-volt battery, 110 volts、110 volts, a 5-volt charger或a 5-volt charger. Written short簡寫的時候 it is V with a capital letter and no dot是大寫V、沒有句點 — 12V, 240 V像12V、240 V — and而 by convention the unit name is lower-case (volt)按照慣例單位名稱小寫（volt）, even though雖然 the letter symbol is capital字母符號是大寫, because因為 it honours a person它是紀念一個人

Everyday electrical talk uses it constantly: travellers ask what voltage a country runs on, since Taiwan uses 110 volts while most of Europe uses 220 to 240, and plugging the wrong device in can destroy it. The related noun voltage means the number of volts, and is what people usually say when speaking generally: "check the voltage", not "check the volts".

Everyday electrical talk日常談到電的時候 uses it constantly常常會用到它: travellers ask what voltage a country runs on旅客會問一個國家用的是多少電壓, since因為 Taiwan uses 110 volts台灣用110伏特 while而 most of Europe uses 220 to 240大部分歐洲國家用220到240, and而 plugging the wrong device in can destroy it插錯設備可能會把它燒壞. The related noun voltage相關的名詞voltage means the number of volts指的是伏特的數值, and而且 is what people usually say when speaking generally一般講話的時候大家通常會說這個字: "check the voltage"像check the voltage, not而不是 "check the volts"check the volts

Note that after a number used as an adjective before a noun, English writes it singular and hyphenated: a nine-volt battery, not a nine-volts battery.

Note that要注意 after a number used as an adjective before a noun當數字被當作形容詞放在名詞前面時, English writes it singular and hyphenated英文會寫成單數並加連字號: a nine-volt battery像a nine-volt battery, not而不是 a nine-volts batterya nine-volts battery
