Electric current is the movement of electric charge in a conductor in one direction due to the influence of external forces.<\/span> Because naturally in a material or substance, the erratic movement of cargo direction.<\/span> Electric charge can be either an electron, ion or keduanya.Arus electricity can occur with media solids, liquids, and gases.<\/span> As you already know, that the electric charge is measured in coulombs (C), where 1 Coulomb is equal to the amount of cargo by a 6.24 x 10 ^{18<\/sup> electrons, and the charge of an electron is e = 1.602 x 10 -19<\/sup> Coulomb.<\/span><\/p>\n}

One Coulomb is a matter of a number of electrons passing through the conductor sauatu every second, while the constant current flow rate at one ampere.<\/span> Electric current in a conductor is a directional movement of electrons number from one end to the other.<\/span> The number of electrons in the Coulomb equal to 6.24 x 10 ^{18<\/sup> electron fruit.<\/span> The flow of one Coulomb per second equals one ampere.<\/span> It’s like a water flow rate in gallons per minute.<\/span><\/p>\n}

Coulomb measure the amount of electrons.<\/span> Amper measuring the rate of flow of electric current.<\/span> Amper not measure the electron.<\/span> But Amper has a relationship with Coulomb 1\/1.<\/span> It means that if there is 10 amperes flows through the same point in one second with 10 Coulomb.<\/span> From the above explanation can be defined that the unit of electric current is coulomb per second.<\/span> However, the unit of electric current that is commonly used is the ampere, where one coulomb per second = one ampere or I = Q \/ t where I is the epitome of an electric current.<\/span><\/p>\n

The units of ampere electric current is taken from the name of Andre Marie Ampere (1775-1836).<\/span><\/p>\n

The movement of electrons on an object during a certain period of time will lead to an energy which is then referred to as an electric current.<\/span> Suppose that in a conductor, if<\/span>
\n – N is the number of free electrons in each cubic meter of conductor<\/span>

\n – A is the cross sectional area of \u200b\u200bthe lawyer-conductivity<\/span>
\n – E is the magnitude of the charge of each electron.<\/span><\/p>\n

Then the volume conductor traversed by the movement of electrons in a time dt is: vAdt and the number of electrons moving in the volume are:<\/span>

\n So the magnitude of the charge that penetrate the conductor cross-section in a time dt is<\/span>
\n dq = nvAedt.<\/strong><\/span>
