unit of electric potential
A unit for measuring how strong an electric force is that pushes electric charge, used in science and electronics.
用法模式：
[something] is [number] volts
常见错误：
Learners often confuse 'volt' with other electrical units like 'watt' or 'amp'. A *volt* measures electric potential (how strong the push on the charge is), an *amp* measures current (how much charge flows), and a *watt* measures power (how fast energy is used). Another mistake is using the singular with numbers, e.g. saying 'five volt' instead of the correct 'five volts'.
