Why copper electrical wires need to be wrapped in plastic?
Copper wires are wrapped in plastic to provide insulation and protection against moisture and other potential damage. The plastic coating helps to prevent short circuits and ensures the proper flow of electricity through the wire.
Why it is easy to charge polythene by rubbing but not copper?
When you rub plastic, you transfer electrons from one material to the other. ... Because plastic is an insulator, the electrons cannot flow through it so they effectively get stuck there they are static
Can copper change its appearance to look silver?
Yes, copper can change its appearance to look silver through a process called plating or coating with a silver-colored material.
What is the name of the black coating that forms on the surface of copper?
copper oxide. when it reacts with the oxygen in the air it produces copper oxide
Is copper 2 chlorate ionic and covalent?
Copper(II) chlorate is an ionic compound. In this compound, the copper ion has a charge of +2 and the chlorate ion has a charge of -1. The ions attract each other through ionic bonds, where electrons are transferred from the copper atom to the chlorate ion.
Why copper electrical wires need to be wrapped in plastic?
Copper wires are wrapped in plastic to provide insulation and protection against moisture and other potential damage. The plastic coating helps to prevent short circuits and ensures the proper flow of electricity through the wire.
What is the name of the black coating that forms on the surface of the copper?
The black coating that forms on the surface of copper is called copper oxide.
What is the chemical name for a green coating on a coin?
For copper or some copper alloys coins the coating is hydrated copper carbonate.
Why it is easy to charge polythene by rubbing but not copper?

What is the plastic coating on the wire called?
Plastic or rubber is used as insulation around electrical wires, keeping them from contacting other parts of a circuit, and from grounding out to conductive materials. Where insulation is removed or damaged, a spark or short could cause fires or other damage.
Can copper change its appearance to look silver?
Yes, copper can change its appearance to look silver through a process called plating or coating with a silver-colored material.
What are telephone made of?
Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.
What object uses both an insulator an conductor?
Elecrical wire is an great example of this. the copper wiring is the conductor of electrons and the plastic coating insulates the wire absorbing some heat from friction and it's impermeable to electrons not allowing them through outside the wire.
Is paper or plastic a better conductor?
Copper is a better conductor of electricity than both paper and plastic. Paper and plastic materials are poor conductors of electricity compared to metals like copper, which have a higher density of free electrons that can carry electric charge more effectively.
What is the predominant carrier of electrical charge in a copper wire?
The predominant carrier of electrical charge in a copper wire is the free electrons within the copper atoms. These free electrons are able to move easily through the lattice structure of the copper, allowing for the flow of electric current.
What year was penny changed in amount of copper?
Midway through 1982, the composition of the US penny changed from 95% copper and 5% zinc to 97.5% zinc and 2.5% copper (in the form of a coating of pure copper over a core of zinc).
What are telephone wires made of?
Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.
