The Ampere

Author: E.E. Kimberly

In the centimeter-gram-second (cgs) system of units, electric current is measured in abamperes. The ampere is the practical unit of current and is equal to one-tenth of an abampere. The ampere may also be defined as that constant current which, when passed through a standard solution of nitrate of silver in water, deposits silver at a rate of 0.001118 gram per second. Also the current is said to be 1 ampere when the rate of electron flow is 6.281018 electrons per second.
