A conductor is a material (usually a metal such as copper) that allows electrical current to pass easily through. This is opposed to an insulator which prevents the flow of electricity through it.
How do electrical conductors work?
Electrical conductors allow electric current to flow easily because of the make up of their atoms. In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied. In general, the best electrical conductors are metals.

Materials that are poor conductors of electricity are called insulators. Some examples are wood, glass, plastics, non-metal elements that are polymers of hydrocarbons.
Why is aluminium is a good conductor of electricity?
Aluminum is a good conductor because it is a metal. In metals, the valence electrons are already detached due to the metallic bonds between atoms. We call these electrons that break the bond with their atom free electrons. Aluminum will always be a conductor, no matter its shape.
Is iron a conductor?
Iron has metallic bonds which is where the electrons are free to move around more than one atom. This is called delocalization. Because of this, iron is a good conductor.

This orientation is important when drawing circuit diagrams to depict the correct flow of electrons. A battery is a device that converts chemical energy directly to electrical energy. It consists of a number of voltaic cells connected in series by a conductive electrolyte containing anions and cations.
