In terms of energy bands, conductors are materials that have partially filled or overlapping energy bands, allowing electrons to move freely throughout the material. In conductors, the valence and conduction bands overlap, creating a continuous band of energy levels that electrons can occupy. This allows electrons to easily move in response to an applied electric field, resulting in the material having high electrical conductivity.
The presence of free-moving electrons in conductors is what allows them to conduct electricity efficiently. When a voltage is applied across a conductor, the electrons can easily move through the material, carrying the electric current. This is in contrast to insulators, which have large energy band gaps that prevent the movement of electrons, and semiconductors, which have a small band gap that can be manipulated to control the flow of electrons.

In solid-state physics, conductors are materials that allow electricity to pass through them easily. This ability is due to the presence of free electrons within the material. In terms of energy bands, conductors have an overlapping valence band and conduction band. This means that there are no forbidden energy levels between the two bands. This allows electrons to easily move from the valence band to the conduction band, creating an electrical current.
The energy band diagram of a conductor is shown below:

In this diagram, the valence band is the lower band, and the conduction band is the upper band. The Fermi level is the energy level at which the probability of finding an electron is 50%. In a conductor, the Fermi level lies in the overlap region between the valence band and the conduction band. This means that there are always some electrons that have enough energy to move from the valence band to the conduction band.
The conductivity of a conductor is determined by the number of free electrons in the material. The more free electrons there are, the more easily electricity can flow through the material. The temperature of a conductor also affects its conductivity. As the temperature of a conductor increases, the number of free electrons increases. This is because the heat energy provides the electrons with enough energy to overcome the potential barrier between the valence band and the conduction band.
Conductors are used in a wide variety of applications, such as electrical wires, cables, and electronic components.
