- Q8A closed circuit....is on.has a break in it.is off.requires no battery.60sEditDelete
- Q9Wires are normally made from copper. This is because....copper has a pretty color.copper is a good insulator.copper is a very good conductor of electricity.copper is a poor conductor of electricity.60sEditDelete
- Q10Why are electrical plugs made of plastic?Plastic is a good electrical conductor.Plastic protects people from electricity.Plastic is stronger than all other materials.Only plastic can be made into the right shape for a plug.60sEditDelete
- Q11A material which is an electrical conductor does what?It allows electricity to pass through it easily.It does not allow electricity to pass through it easily.It allows heat to travel through it easily.It does not allow heat to travel through it easily.60sEditDelete
- Q12Wires are usually coated in plastic because....plastic is an insulator.plastic bends and rubber does not.plastic helps the wires conduct electricity.plastic can be lots of different colors.60sEditDelete
