Current+electricity

=Current electricity=

Fundamentally, an electrical current is an electron flow. As a physical quantity, current is the rate at which charge flows past a point on a circuit. In metallic solids, electricity flows by means of electrons, from lower to higher electrical potential.

A conventional current, however is defined to flow in the same direction as positive charges. So in metals where the charge carriers (electrons) are negative, conventional current flows in the opposite direction as the electrons.

=Electrical current=Q/t=

Current is a rate quantity. Mathematically, it is expressed by :

Whereby I refers to current, Q refers to electrical charge, Coulombs, and t refers to time. The standard metric unit for current is the **ampere**. Ampere is often shortened to //Amp// and is abbreviated by the unit symbol **A**. A current of 1 ampere means that there is 1 coulomb of charge passing through a cross section of a wire every 1 second.
