Meanwhile, a French physicist named André-Marie Ampère was experimenting with some wires, ... you may have noticed that there's an integral on the left-hand side of the equation for Ampere's law.

Instead, physicists would like to define the ampere by creating an extremely precise source of electric current capable of delivering one electron at a time. Although researchers have already tried to ...

In November 2022, Renault announced Ampere, a new EV and software standalone business unit named after French physicist and mathematician André-Marie Ampère.

Physicists have tracked electrons crossing a semiconductor chip one at a time — an experiment that should at last enable a rational definition of the ampere, the unit of electrical current.
