AMPWhat is AMP? Amperage is a unit of electrical flow. It's the rate of electromotive flow through a conductor (wire). This is somewhat analogous to the volume quantity flow rate of water through a pipe. See Volt Amp Watt animations. Amperage rating of bulb is measured at bulbs rated voltage. Published specs for amperage typically have a tolerance of plus or minus 10%. To calculate the amperage; if you know the voltage and wattage of the circuit, then amperage equals wattage divided by voltage (amp = watt / volt) (example, 5 amps = 60 watts / 12 volts. 1 amperes = 1 coulomb of electrons passing a point of a conductor in one second. 10 amperes = 1 abampere. The ampere is named after Andre Marie Ampere, a professor of mathematics in the Polytechnic school in Paris in year 1820. references for this page: AMP, AMPERAGE, AMPERE, AMPERES, AMPS, CURRENT, ELECTRICAL CURRENT references to this page: ABAMPERE, BALLAST, CHARACTERISTIC CURVES, CONVERSION TABLE, ELECTRIC DISCHARGE LAMP, ELECTROMAGNETIC BALLAST, ELECTRONIC BALLAST, GLOW LAMP, HALOGEN BULB, INCANDESCENT BULB, RE-RATE, VOLT, VOLT AMP WATT ANIMATIONS, WATT |
