ampere

An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current.

The ampere is named after Andre Marie Ampere, French physicist (1775-1836).

This definition is wrong.

The definition maybe is of a Coulomb instead. The Ampere should be measured through the force between two wires.

This is the wrong definition - The definition maybe for Coulomb.

Amps = Watts/Volts
Volts = Watts/Amps
Watts = Amps*Volts

Actually, the definition provided is correct, since an ampere is the rate of flow of electrons, or, technically, charge carriers. It is measured by the attractive force created by the magnetic field created around a conductor when a current flows in the conductors.

You contradict yourself.

The ampere has NEVER been defined in terms of the rate of flow of electric charge! Wherever did you find that definition?

it was defined as one coloumb per second by the International System of Units (SI Units) what definition are you using?

Queqweqwe, would you care to specify  WHEN it was defined as a 'coulomb per second' in SI? Since 1947, the ampere has been defined, in SI, in terms of the force between a pair of parallel, current-carrying conductors. Before 1947, it was defined in terms of the mass of silver deposited by electrolysis. As far as I am aware, it has NEVER been defined as a 'coulomb per second'... certainly not in our lifetime! As the ampere is a base SI unit, and the coulomb is a derived SI, clearly the ampere CANNOT be defined in terms of a coulomb!!! This year, the ampere is to be redefined in terms of the number of elementary charges transported per second, so STILL not in terms of the coulomb.
