伏特(Volt)是电压(Voltage)的单位。Voltage和Volt这组词,命名违背了物理量的命名规则:量和单位的名不应该相互refer。比如电流的单位是安培、电阻的单位是欧姆。
The name "voltage", commonly used in the English language, is an exception from the principle that a quantity name should not refer to any name of unit.
立方兄几次写到:“电压(voltage)就是个unit 单位”,可能就是被这词干扰了。不过他也老是把电荷量(Electrical Charge)和库伦(Coulomb)混为一谈,又好像不单是词的问题。
