A substance that is a poor conductor. Is anything that is not metal. Such things as an insulator that includes wood, plastic, polystyrene foam, fabric, gas
A non metal as it does not have free moving delocalized particles which allow a current to flow. Therefore it will be a poor conductor of heat and electricity.
These elements are called insulators.
rubber
Insulator
non metals has no luster and is a poor conductor
Examples are many organic compounds.
poor
All metals conduct electricity to some extent. Chromium isn't an especially good conductor, but it does conduct.. so we can say that it is a poor conductor.
a poor conductor of heat. a good conductor of heat will allow the heat to pass though the flask and escape cooling the tea. so a poor conductor just to clarify.
A conductor and a switch
Wood Rubber
A Poor Conductor of heat is usually called an insulator.
That is called an insulator.
It is a substance that does not readily ionize when dissolved or melted and is a poor conductor of electricity and is a substance that does exist in an ionic form in an aqueous solution.
It is called as conductor. Ex:Iron copper,etc.
conductor
Many organic compounds.
A dielectric material is a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic fields
That would be an insulator.
A substance that lets electricity flow through it is called a conductor (or sometimes, to be more explicit, it is called an electrical conductor). Substances which do not permit the flow of electricity are called insulators.
helium is an insulator (poor conductor) of heat
