They are insulators.
most non ferrous materials are poor conductors with exceptions
normally called insulators
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
Yes.
These are called insulators.
Conductor Some materials are conductors of Heat OR Electricity. But the property is not the same for one material; example glass is a good conductor of heat but a poor conductor of electricity.
Materials that are poor conductors of heat are Plastic and Wood "example."
nonmetals
Non-metals are mostly poor conductors, or so called insulators. Metals conduct electricity. These have free electrons which may move freely around the surface of the element.
plastic, glass and rubber
Coins are made of metal and metals are good conductors of electricity.
yes
