Question

Give reasons for the following statement.
Copper and aluminium wires are used In electrical fittings.

Answer 1

• Metals are generally hard solid substances that have a shiny luster and are good conductors of electricity.
• For example - Sodium$\left(\mathrm{Na}\right)$, Silver$\left(\mathrm{Ag}\right)$, etc.
• Metals have the property to convert into sheets as well as into wires.
• The tendency of an element to convert into wires is known as ductility.
• Copper$\left(\mathrm{Cu}\right)$ and Aluminium$\left(\mathrm{Al}\right)$ are excellent electrical conductors. They have a low resistance, allowing current to flow freely through them.
• As a result, they're employed to produce electrical transmission cables.
