What are materials that allow electric charges to flow through them easily?

Conductors

Conductors are materials that allow electric charges to flow through them easily. This is because conductors have free electrons that can move easily when an electric field is applied. Insulators, on the other hand, do not allow electric charges to flow through them easily as they have few free electrons. Solvents and insulants are not related to electric conductivity and do not facilitate the flow of electric charges.
