Electric Current is the flow of electrons in a conductor under the influence of voltage. Electron current flow is the flow of electrons from the negative terminal of a voltage source to the positive terminal of a voltage source.
Electric current is defined as quantity of electrons flowing past a point over time. In mathematical terms, this is defined as:
Where: I = Current Units: Amperes (A) Q = Charge Units: Coulombs (C) t = Time Units: Seconds (s)
A current of 1 Ampere is defined as the quantity of 1 Coulomb of Charge moving past a point over a Time period of 1 second.
