definition of: AMP

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.
