A unit of electric current equal to 10 amperes, used in the centimeter-gram-second system of measurement.
From 'ab-' (absolute) and 'ampere,' abbreviated from 'abampere.' Created in the 19th century as scientists developed standardized units for measuring electricity.
Scientists created 'abamp' as a shorthand for 'absolute ampere'—it's part of an older measurement system that was gradually replaced, but the word still appears in physics history books.
