Subject :Physics Class : Class 6
There is a variety of materials that are used to make components of electrical circuits. These materials have good electrical conductivity. Inspite of having the largest conductivity among metals, silver is not used to make electric wires. Aluminium and copper are generally used to make electric wires. Not only conductors, insulators are also important. The electrical wires are covered with plastic and rubber like materials. This is used to prevent short circuit and also to protect the user.
