André-Marie Ampère (UK: / ˈ æ m p ɛər /, US: / ˈ æ m p ɪər /; [1] French: [ɑ̃dʁe maʁi ɑ̃pɛʁ]; 20 January 1775 – 10 June 1836) [2] was a French physicist and mathematician who was one of the founders of the science of classical electromagnetism, which he referred to as electrodynamics.
As of the 2019 revision of the SI, the ampere is defined by fixing the elementary charge e to be exactly 1.602 176 634 × 10 −19 C, [6] [9] which means an ampere is an electric current equivalent to 10 19 elementary charges moving every 1.602 176 634 seconds or 6.241 509 074 × 10 18 elementary charges moving in a second.

The Ampère Museum is a museum of the history of electricity dedicated to André-Marie Ampère (1775–1836). The museum is located in Poleymieux-au-Mont-d'Or at approximately 15 km (9.3 mi) from Lyon by road and is housed in the house where André-Marie Ampère spent part of his youth.

In Irish and Scottish Gaelic, the character ⁊ (U+204A ⁊ TIRONIAN SIGN ET) is used in place of the ampersand. This character is a survival of Tironian notes, a medieval shorthand system. This character is known as the Tironian Et in English, the agus in Irish, and the agusan in Scottish Gaelic.
Ampere is an electric vehicle and software company formed in 2023 by Groupe Renault as part of the third phase of its "Renaulution" recovery plan. Renault originally planned to spin off Ampere and proceed with an IPO but canceled these plans in January 2024 but is operated as an autonomous business. [ 4 ]
