What is an example of a poor conductor?
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.
