Types and properties of Conductor

Conductivity is a material property that allows it to carry electricity through it. Conductors, insulators, and superconductors are the three types of materials classed by conductivity.Conductors are materials with high electron mobility, while insulators have low electron mobility. A good electrical conductor allows electrons to flow freely.
