A material can be a poor conductor of heat, electricity, or both.

A poor conductor means that the substance will not easily conduct heat or electricity (or both) as easily as a conductor.

For example, sand is a poor conductor of heat and electricity. During the daytime, when the sunlight hits the sand, it traps the heat instead of conducting it. Similarly, it does not conduct electricity. In comparison, copper is a conductor of both heat and the electricity, and hence we can use utensils made of copper for cooking and copper wires for electrical applications.

Non-metals are generally bad conductors or insulators. Metals, on the other hand, are good conductors.

Some other examples of poor conductors of electricity are mica, paper, wood, glass, rubber, Teflon, etc. Some examples of poor conductors of heat are air, lead, etc.

Hope this helps.

Poor conductors are any material that does not conduct electricity, heat or both very well and are generally known as insulators.

Non-metals are typically insulators (poor conductors) while metals, i.e. Copper, are very good conductors which is why they are used in cookwear and electric wiring.

Examples of poor conductors:

wood, rubber, air, paper etc.

When speaking in terms of a physical conductor, a poor physical conductor is one that does not rapidly or efficiently transfer energy in the form of heat or electricity.

With that definition you can identify good and bad conductors around you quite easily. Metals such as copper are good conductors—that is why they are used in electrical wiring and cookware, while materials such as rubber are poor conductors. That’s why wires are insulated with rubber or rubber-like plastics.

Conductivity can vary between electrocity and heat, so it is important to identify the purpose of the conductor. Glass, for example, can conduct heat fairly well but not electricty.

The property of conductivity is determined by the molecular structure of the substance. Metals generally allow the flow of electrons (electrical conductivity) while nonmetals resist the flow.
