amperage definition
A unit of electric current in the meter-kilogram-second system, equal to the current that, flowing in two parallel wires one meter apart, produces a force of 2 × 10-7 newtons per meter. A unit in the International System specified as one International coulomb per second and equal to 0.999835 ampere. the magnitude of an electric current measured in amperes, esp the rated current of an electrical component or device. Word Origin and History for amperage. n. strength of an electric current, 1889, from ampere on model of voltage. TIG welding requires a TIG welding power supply, work clamp, TIG torch, remote amperage control device (usually foot or fingertip control), tungsten electrodes, filler rods to match the base metal, gas cylinder and gas supply, plus hoses and regulators. Definition of AMP. : a nucleotide C10H12N5O3H2PO4 composed of adenosine and one phosphate group that is reversibly convertible to ADP and ATP in metabolic reactions —called also adenosine monophosphate, adenylic acid — compare cyclic amp. the basic SI unit of electric current; the constant current that, when maintained in two parallel conductors of infinite length and negligible cross section placed 1 metre apart in free space, produces a force of 2 × 10–7 newton per metre between them. 1 ampere is equivalent to 1 coulomb per second. 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. Electric current through any given cross-section (such as a cross-section of a wire) may be measured as the amount of electrical charge moving through that cross-section in one second. One ampere is equal to a flow of one coulomb per second, or a flow of 6.28 × 1018 electrons per second. ­The­ three most basic units in electricity are voltage (V), current (I, uppercase i) and resistance (r). Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size.
