Insulators and Conductors

Insulators: An insulator is a material of such low conductivity that the flow of current through it is negligible. Some ideas of insulators are things such as wood, yarn, fleece, another things with out an electric flow.

An **insulator**, also called a //[|dielectric]//, is a material that resists the flow of [|electric current]. An insulating material has atoms with tightly bonded [|valence electrons]. These materials are used in parts of electrical equipment, also called //insulators// or //insulation//, intended to support or separate electrical [|conductors] without passing current through themselves. The term is also used more specifically to refer to insulating supports that attach [|electric power transmission] wires to [|utility poles] or [|pylons]. Some materials such as [|glass], [|paper] or [|Teflon] are very good electrical insulators. A much larger class of materials, for example rubber-like polymers and most plastics are still "good enough" to insulate [|electrical wiring] and [|cables] even though they may have lower bulk [|resistivity]. These materials can serve as practical and safe insulators for low to moderate voltages (hundreds, or even thousands, of [|volts]). -Wikipedia

Conductor: Conductors are a substance, body, or device that readily conducts heat, electricity, sound, etc. Some conductors are water, metal, copper, and other things that produce electricity.
