Ampere

The ampere (SI unit symbol: A), often shortened to "amp", is the SI unit of electric current (dimension symbol: I) and is one of the sevenSI base units. It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

The ampere is equivalent to one coulomb (roughly 7018624100000000000♠6.241×10¹⁸ times the elementary charge) per second. Amperes are used to express flow rate of electric charge. For any point experiencing a current, if the number of charged particles passing through it — or the charge on the particles passing through it — is increased, the amperes of current at that point will proportionately increase.

The ampere should not be confused with the coulomb (also called "ampere-second") or the ampere-hour (A⋅h). The ampere is a unit of current, the amount of charge transiting per unit time, and the coulomb is a unit of charge. When SI units are used, constant, instantaneous and average current are expressed in amperes (as in "the charging current is 1.2 A") and the charge accumulated, or passed through a circuit over a period of time is expressed in coulombs (as in "the battery charge is 7004300000000000000♠30000 C"). The relation of the ampere to the coulomb is the same as that of the watt to the joule, and that of metre per second to metre.

Amp Energy

Amp Energy (or simply Amp) is an energy drink brand produced and owned by PepsiCo. At the time of its introduction in 2001, Amp Energy was initially distributed under the Mountain Dew soft drink brand. Since 2009, it has been produced and labeled under its own stand-alone trademark name. The beverage is packaged in both 16-ounce and 24-ounce cans, and is sold in the United States, Canada and the United Kingdom. As of 2009, Amp Energy was the number four energy drink brand in the U.S. in terms of overall retail sales.

Flavors

The original formulation of Amp Energy was positioned as a flavor extension of the Mountain Dew brand, and in 2001 its label read "Amp Energy Drink from Mountain Dew". In 2008 the label design was changed to contract the product name to a more concise "Amp Energy", with the Mountain Dew logo being shifted to the lower portion of the cans. In Amp's 2011 redesign, the Mountain Dew logo was taken off the cans completely. According to beverage industry commentators at the time, this labeling update was enacted with the intent of "placing a stronger emphasis on the 'Amp Energy' brand and less on its Mountain Dew roots". Amp Energy Original contains taurine, B-vitamins, guarana, ginseng and maltodextrin. 8.4 fluid ounces of Amp contains 74 milligrams of caffeine.
