Copper cables are reputed to carry electricity well.
Material with high resistance
Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.
The epsilon r value, also known as the relative permittivity, indicates how well a material can store electrical energy when placed in an electric field. It is a crucial factor in determining the dielectric properties of a material because it influences the material's ability to resist the flow of electric current and store electrical charge. A higher epsilon r value means the material is a better insulator and can store more electrical energy, while a lower value indicates a material that conducts electricity more easily.
The word is "thermal conductor."
Silver is a shiny solid that conducts electricity very well due to its high electrical conductivity. It is commonly used in electrical applications like circuits and connectors.

a conductor does, while an insulator poorly conducts thermal energy!

High electrical conductivity means that a material can easily conduct electrical current. This is due to the presence of free-moving charged particles, such as electrons, that can carry the electrical charge through the material with little resistance. Materials with high electrical conductivity are commonly used in electrical wiring, circuits, and electronic devices.
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
A material with a good thermal conductivity or a thermal conductor.

One material that conducts thermal energy poorly is Styrofoam. This material has a low thermal conductivity due to its high concentration of trapped air pockets, which hinders the transfer of heat. This property makes Styrofoam a good insulator for keeping things cool or warm.
semiconductor
The permittivity of a material, represented by the symbol epsilon r, is important in electrical engineering because it determines how well a material can store electrical energy and how it interacts with electric fields. Materials with higher permittivity can store more electrical energy and are often used in capacitors and other electronic components to control the flow of electricity.
