________________________________

What are Conductors?

• Conductors are the materials or substances which allow electricity to flow through them.

• They conduct electricity because they allow electrons to flow easily inside them from atom to atom.

• Also, conductors allow the transmission of heat or light from one source to another.

Examples of Conductors

• Material such as silver is the best conductor of electricity. But, it is costly and so, we don’t use silver in industries and transmission of electricity.

• Copper, Brass, Steel, Gold, and Aluminium are good conductors of electricity. We use them in electric circuits and systems in the form of wires.

• Mercury is an excellent liquid conductor. Thus, this material finds use in many instruments.

• Gases are not good conductors of electricity because the atoms are quite far away. Thus, they are unable to conduct electrons.

What are Insulators?

• Insulators are the materials or substances which resist or don’t allow the current to flow through them.

• In general, they are solid in nature.

• Also, insulators are finding use in a variety of systems. As they do not allow the flow of heat.

• The property which makes insulators different from conductors is its resistivity.

Examples of Insulators

• Glass is the best insulator as it has the highest resistivity.

• Plastic is a good insulator and it finds its use in making a number of things.

• Rubber is a common material used in making tyres, fire-resistant clothes and slippers. This is because it is a very good insulator.
