Detailed Solution

The above statement is True.
Copper and aluminium are good electrical conductors with low resistance, allowing electricity to flow through them freely. They have a large number of free electrons due to their metallic characteristics. These metals are ductile and resistant to corrosion. Furthermore, copper is the most conductive metal available and is less expensive than silver. Copper and aluminium wires are commonly used for power transmission because they lose less power during transmission. All metals, to some extent, conduct electricity. However, some metals conduct electricity more efficiently than others. Copper, silver, aluminium, gold, steel, and brass are examples of electrical conductors. As a result, copper and aluminium wires are frequently employed for power transmission.
