Copper is used in electrical wiring. Using your knowledge of the atomic structure in copper, explain how the arrangement of atoms in copper enables it to be made into wires.

Why copper and aluminium wires are usually employed for electricity transmission?

Assertion (A): The connecting wires are made of copper.Reason (R): The electrical conductivity of copper is high.

In a copper wire, the flow of current is made up of which of the following?A ionsB electronsC protonsD neutrons

At the same temperature, two wires made of pure copper have different resistances. The same voltage is applied at the ends of each wire. The wires may differ inCheck all that apply.View Available Hint(s)for Part Alength.cross-sectional area.resistivity.amount of electric current passing through them.

Which one of the following is the reason why pure metals are good electrical conductors?The movement of delocalised electrons.The arrangement of metal atoms in layers.The strong force of attraction between metal ion and delocalised electron.The high melting and boiling points.
