Note
An ordinary -s plural that everyday speech usually clips to amps: a fifteen-amp breaker, a load of thirty amps. The symbol never takes a plural, so fifteen amperes is written 15 A, not 15 As. When the unit works as a modifier before a noun it stays singular and is hyphenated, as in a twenty-ampere circuit. After the noun it takes the plural: a circuit rated at twenty amperes.
