What are conductors and what are insulators? - Presentation

Conductors and insulators are fundamental concepts in understanding electricity. Conductors are materials that permit electricity to flow through them easily. This characteristic makes them essential in the creation of various electrical components. Common conductors include metals such as copper, iron, and steel, which are used in everyday items to enable the efficient transfer of electrical current. For example, the metallic parts of plugs and the filament in light bulbs are made from these materials, allowing electricity to pass through and power devices or illuminate spaces.

On the other hand, insulators are materials that do not allow electricity to flow through them. These include substances like plastic, wood, glass, and rubber. Insulators play a crucial role in electrical safety by preventing the passage of electric current where it is not wanted. This is why electrical wires are commonly coated with plastic insulation, safeguarding against the risk of electrocution. Understanding the difference between conductors and insulators is vital for safely managing and utilising electricity in our daily lives.
