Draw a circuit showing that metals are the pure conductors of electricity.

There are practically two things that affects conductivity.
First, and foremost: Free charges. The moment you add an electric field to a material, this material will respond to it. In materials with free electrons, those electrons will move the opposite direction of the electric field. When they do, the absence of those electrons will create a new electric field and more electrons will flow from other parts of material to fill the gap.
The 2nd thing that counts is when there’s everything on the road associated with conduction. Electron is, all things considered, a particle. If it keep “colliding” whilst flow, it's going to loose energy in the form of temperature. If there’s a reasonably free lane, like in a mono-crystalline structure, then it will totally lose small power because moves.
Metallic bound is made of metals bonding each other in crystalline structures with clouds of electrons streaming easily within their midst. If you place it underneath the aftereffect of an electromagnetic area, those electron clouds will respond consequently while loosing small power.
If we discuss quantum mechanics, metals are good conductors simply because they don’t have a band gap, that is, the metal valence musical organization (the power levels where electrons participate in an atom) is interwoven along with its conduction band (the power degrees of a “free” electron).
