CORRIENTE ELÉCTRICA

All matter is composed of atoms.Every atom is composed of a nucleus made up of one or more protons and usually an equal or similar number of neutrons. One or more electrons surround the nucleus.The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge.

When an external force is exerted, in some materials, electrons weakly bound to the nucleus travel through the material producing a phenomenon called electricity. For this phenomenon to occur, all electrons need to move in the same direction and in an orderly fashion.
