State two advantages of each of the following materials used in electrical cables: Copper, rubber. (4 marks)Oct/Nov. 2022

Copper:

1. High electrical conductivity: Copper has a high electrical conductivity which makes it an ideal material for electrical cables as it allows for high energy transmission with minimal energy loss.
2. Durability: Copper is a durable material that can withstand high temperatures, making it suitable for use in high-temperature environments.

Rubber:

1. Insulation: Rubber is a good insulator, which makes it an ideal material for electrical cables as it prevents electrical energy from escaping and keeps people safe.
2. Flexibility: Rubber is a flexible material, which makes it easy to bend and shape into different forms. This makes it suitable for use in applications where cables need to be bent or twisted.
