Coins are made of metal and metals are good conductors of electricity.
the conductors of roads
conductors are generally are made of metals and naturally metals are of shiny and so u can tell that all conductors of heat shiny
They are made using both conductors and insulators: conductors where you do want the electricity to be able to flow and insulators where you want to prevent the electricity from flowing.If they were made using just one or the other, they could not perform their intended functions.
mostly metals
Because metal are conductors.
Keys are usually made from some metal or alloy. If they are, they are good conductors, both of heat and of electricity.
Serving spoons are conductors because they are made of metal and any metal is a conductor
They should be made from insulating material.
Copper
Depends on what they're made of, not what they are.Anything made of a conducting material is a conductor, whatever it is.Anything made of an insulating material is an insulator, whatever it is.Material properties - conducting or insulating - is more important than shape.Scissors are generally - but not always - made of metal.And metals are usually conductors, making the scissors conductors.But a scissor might have plastic handles. Plastic is usually an insulator, which would make the handles insulators.
