## AMP: Ampere

AMP is an abbreviation of "Ampere". It is the base unit of electric current in the International System of Units (SI). It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, regarded as the father of electrodynamics.

• The International System of Units describes the ampere in terms of other base units by determining the electromagnetic force between electrical conductors carrying electric current.
• The former CGS measurement system had two different definitions of current, one fundamentally similar to the SI's and the other using electric charge as the base unit, with the unit of charge described by determining the force between two charged metal plates.
• The ampere was then described as one coulomb of charge per second. In SI, the unit of charge, the coulomb, is described as the charge holding by one ampere during one second.
On 20 May 2019, the latest definitions, in terms of never changing constants of nature, particularly the elementary charge, took effect.

### History

• The ampere is named after French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and put down the establishment of electrodynamics.
• In appreciation and acknowledgment of Ampère's contributions to the establishment of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, recognized the ampere as a standard unit of electrical measurement for electric current.
• The ampere was formerly described as one-tenth of the unit of electric current in the centimeter–gram–second system of units. That unit, now known as the abampere, was described as the amount of current that produces a force of two dynes per centimeter of length between two wires one centimeter away from each other. The size of the unit was selected so that the units originated from it in the MKSA system would be suitably sized.
• The "international ampere" was an early consciousness of the ampere, described as the current that would put down 0.001118 grams of silver per second from a silver nitrate solution. Afterward, more precise measurements exposed that this current is 0.99985 A.
• As power is described as the product of current and voltage, the ampere can, on the other hand, be articulated in terms of the other units using the relationship I = P/V, and therefore 1 A = 1 W/V.
• Current can be measured by a multimeter, a piece of equipment that can measure electrical voltage, current, and resistance.
