Materials known as 'insulators' would be the worst. They include such
substances as glass, ceramic, rubber, plastic, wood, and pure water.
They are insulators.
most non ferrous materials are poor conductors with exceptions
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.
Nonmetals would not work because they are poor conductors of electricity
Materials that are poor conductors of heat are Plastic and Wood "example."
plastic, glass and rubber
Poor conductors of heat are generally also poor conductors of electricity. These would include most gases, ceramics and man-made plastics. A vacuum will not conduct heat either.
Coins are made of metal and metals are good conductors of electricity.
yes
Some nonmetallic materials are good conductors, graphite being an example. In this form, it is considered a semi-metal for that reason. Normally, however, nonmetals are not good electrical conductors.
