What is an international ampere?
The ampere (/ ˈ æ m p ɛər / AM-pair, US: / ˈ æ m p ɪər / AM-peer; symbol: A), often shortened to amp, is the unit of electric current in the International System of Units (SI). One ampere is equal to 1 coulomb (C) moving past a point per second.
Ampere, unit of electric current in the International System of Units (SI), named for 19th-century French physicist Andre-Marie Ampere. It represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt.

- Ampere meter, commonly known as Ammeter is an electrical instrument used to measure electrical current in Amperes.
- Yes, the value of ampere can be negative.
- Ampere is required to quantify the current flowing in a system.
- When an ammeter is connected in parallel it becomes a short circuit path allowing all the current to flow through it which maybe lead to the burnin...
André-Marie Ampère ( UK: / ˈɒ̃pɛər, ˈæmpɛər /, US: / ˈæmpɪər /, [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".
The ampere is one of several electrical charge units used to measure the electromagnetic force between straight parallel conductors carrying electric current. One ampere is equal to one coulomb of charge (or one newtons per metre) moving past a given it in one second.
The meaning of AMPERE is the practical meter-kilogram-second unit of electric current that is equivalent to a flow of one coulomb per second or to the steady current produced by one volt applied across a resistance of one ohm.
The ampere is that constant current which—if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in vacuum—would produce between these conductors a force equal to 2 × 10 − 7 newtons per meter of length.
