unit:A
$\textit{Ampere}$, often shortened to $\text{amp}$, is the SI unit of electric current and is one of the seven SI base units defined as: $$\text{A} \equiv \frac{\textit{C}}{\textit{s}} \equiv \frac{\textit{coulomb}}{\textit{second}} \equiv \frac{\text{joule}}{\text{weber}}$$ Note that SI supports only the use of symbols and deprecates the use of any abbreviations for units.
