One ampere is equal to the electric force of one volt acting across the resistance of one ohm. One ampere is approximately equivalent to 6.24150948x10 raised to the 18 power elementary charges, such as electrons passing a set point in a circuit. (It is proportional to the quantity of electrons flowing through a conductor past a given point in one second.)
Ampere
An ampere is the SI quantitative electrical charge movement which is the basic unit of measurement for current flow in an electric circuit, or rate of flow of electrons through a conductor, named after French physicist Andre Marie Ampere (1775-1836). Ampere is symbolically characterized by the letter and sometimes when used in formulas. Most household appliances use 15 or 20 amps of power. Amps are what give electricity its shock.
