What helps metal to flow electricity ?

Dear Student,

Free electrons present inside a metal is responsible for the flow of electricity.

​​​​​​Current is generated due to the flow of electrons. initially electrons in a metal move randomly but when the circuit is closed the free electrons begin to move from negative to positive terminal which is a rough process as in their way they collide with many atoms and ions due to which the heat is produced as kinetic energy of electrons gets transferred to the atoms which vibrate with large amplitudes and hence heat is produced.

Dear student,

Metals contain free moving delocalized electrons. When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.

Dear student,
 

Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.

Because valence electrons are free to move, they can travel through the lattice that forms the physical structure of a metal. Under an electric field, free electrons move through the metal much like billiard balls knocking against each other, passing an electric charge as they move.

Regards.
