What 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.
