How does electricity flow?

In: Consumer Electronics [Edit categories]

Electric current is a flow of electric charge. The electric charge in a current is carried by electrons that orbit the nuclei of atoms. Each electron carries a small electric charge. When a stream of electrons moves from atom to atom, the flow of the charge they carry is called electric current.

Each atoms has negative and positive electric charges which, like magnetic poles, attract each other. When there is a difference in the overall charge of atoms between the two ends of a wire, the negatively charged electrons will flow toward the positively charged end of the wire, creating electric current.
