Ampere definition. Ampere or amp (symbol: A) is the unit of electrical current. The Ampere unit is named after Andre-Marie Ampere, from France. One Ampere is defined as the current that flows with electric charge of one Coulomb per second. 1 A = 1 C/s.
Abbreviation: amp. The amperage, on the other hand, is that of the six cells combined, or 150. Voltage, amperage, and watt or kilowatt are the terms in common use. Then he defines the wave-form, voltage, and amperage entering the circuit and defines whatever is coming out. The name plates on electric motors indicate the amperage at full load. Then the voltage is lowered to a suitable rate, and the amperage raised in proportion, by special machinery, at the point of use.
