The metal lead is already a conductor: it is used on battery connections in automobiles. However, a coating of gold would make it a better conductor of electric current.
They become coated with lead sulfate.
Copper is a conductor, so and pennies are coated in copper.
Conductor
No. In fact it is used as an insulator.The copper wire, used in transformers and other similar wound coils, are coated in varnish, to act as an insulator between each wire.
Plastic is a bad conductor of electricity. Metals are good conductors of electricity. You get the metal wires coated by plastic. So when you touch the wire, you do not get the electric current. This nature of the plastic protects you from getting electrocuted.
A bare conductor is a conductor that does not have any type of insulation covering it. Insulated conductors (also known as coated) have a covering that protects them from outside sources.
human body is good conductor of electricity.For our safety electric tool are coated with insulating materials.
The coated instruments do not conduct the electricity used during the LEEP.
Plastic does not conduct electricity.
Aluminium hangers do conduct electricity, as aluminium is a good conductor of electricity. The reason you may not experience an electric shock when touching an aluminium hanger is because it is often coated with a non-conductive material, such as paint or plastic, which prevents direct contact with the aluminium.
electrician tools must be insulated so that they dont get electrocuted
harddisks are constructed from an aluminum platter (conductor) coated with a magnetic metal oxide (insulator)floppy discs are constructed from a plastic sheet (insulator) coated with a magnetic metal oxide (insulator)however the function of computer disks in no way depends on the property of being a conductor/insulator, only on its ability to retain tiny magnetic domains while permitting them to be easily modified.
