The ampere (SI unit symbol: A), often shortened to amp, is the SI unit of electric current (quantity symbol: I,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. Note that SI supports only the use of symbols and deprecates the use of any abbreviations for units.
In practical terms, the ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6.241 × 1018electrons, or one coulomb per second constituting one ampere.
The practical definition may lead to confusion with the definition of a coulomb (i.e., 1 amp-second), but in practical terms this means that measures of a constant current (e.g., the nominal flow of charge per second through a simple circuit) will be defined in amperes (e.g., "a 20 mA circuit") and the flow of charge through a circuit over a period of time will be defined in coulombs (e.g., "a variable-current circuit that flows a total of 10 coulombs over 5 seconds"). In this way, amperes can be viewed as a flow rate, i.e. number of particles (charged) transiting per unit time, and coulombs simply as the number of particles.

Genres: Sci-Fi,There comes a time when questions end. The page unread, a canvas blank. Answers fail, I can't relate. This is the time when questions end. Yours is a dialogue that I cannot erase. So hang tight to your fears and hold hands with silence. The old ghosts still inhabit the space between your bed and the wall. You've written your own history. This is the bed you've made, and I refuse to tuck you in.
