## Why ampere is a base unit?

Starting on May 20, 2019, the ampere is based on **a fundamental physical constant**: the elementary charge (e), which is the amount of electric charge in a single electron (negative) or proton (positive). The ampere is a measure of the amount of electric charge in motion per unit time ― that is, electric current.

## Is Joule a SI unit?

**The SI unit for energy** is the joule (J): 1 J=1 newton metre (N m).

## Is coulomb a SI unit?

Coulomb The coulomb is **the SI unit for a quantity of charge**. One electron carries an elementary charge, e, of 1.602 x coulombs; therefore, the charge carried by 6.24 x 10 unit charges is one coulomb.
