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.
Yes, cotton thread by itself is not a good conductor of electricity because it is an insulator. However, if the cotton thread is coated or infused with a conducting material like metal, it can become a conductor of electricity.
A screw is typically made of metal, which is a conductor of electricity. However, if the screw is coated with a non-conductive material like plastic or rubber, it can act as an insulator.
Copper is a conductor, so and pennies are coated in copper.
Paper is generally not a good conductor of electricity due to its high resistance. However, paper can become conductive when it is coated with conductive materials like graphite or silver ink. Overall, paper is considered to be an insulator rather than a conductor.
Keys are usually made from some metal or alloy. If they are, they are good conductors, both of heat and of electricity.
Yes, a spoon is typically made of metal, which is a conductor of electricity and heat. However, in terms of electricity, a spoon can act as an insulator if it is coated with a non-conductive material like plastic.
When a lead acid battery produces electricity, both electrodes become coated with lead sulfate. This is a result of the chemical reaction that occurs during the discharge process. Recharging the battery converts the lead sulfate back into lead dioxide and metallic lead.
Wire can be either an insulator or a conductor, depending on its material and properties. Copper wire, for example, is a good conductor of electricity, while rubber-coated wire is used as an insulator to protect against electric shocks.
Conductor
A piece of cloth is typically an insulator because it does not allow electricity to flow easily through it. Cloth is made up of materials like cotton or polyester, which are poor conductors of electricity. However, if the cloth is coated or soaked in a conductive material, then it may act as a conductor.
No, binder clips are not conductors of electricity because they are made of metal and coated with a non-conductive material such as plastic. This prevents the flow of electric current through the binder clip.
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.
