The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics.In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of ...
The ampere or amp (symbol A) is the base unit of electric current in the International System of Units. Ampere or Ampère may also refer to: People
The SI unit of electric current, the ampere (A), is named after him. His name is also one of the 72 names inscribed on the Eiffel Tower. The term kinematic is the English version of His cinématique, [3] which he constructed from the Greek κίνημα kinema ("movement, motion"), itself derived from κινεῖν kinein ("to move").

"The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 × 10 −19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆ν Cs." [1]
PARIS (Reuters) -Renault's electric vehicle unit Ampere said on Monday it would include lithium iron phosphate (LFP) technology in its plans to mass produce EVs, teaming up with LG Energy Solution ...
In the International System of Units (SI), electric current is expressed in units of ampere (sometimes called an "amp", symbol A), which is equivalent to one coulomb per second. The ampere is an SI base unit and electric current is a base quantity in the International System of Quantities (ISQ).
