Electric current refers to the flow of electrons through a conductor. The SI unit for electric current is Ampere.
[edit] Electron flow
In practical circuit theory, current is considered to flow from nodes of higher electric potential to nodes of lower electric potential. However, the direction of the electron flow is from lower to higher electric potential, as a node with lower potential have a larger deposit of electrons compared to a node with higher potential.
