Differentiate, with examples, between an electrical insulator and an electrical conductor.
Worked Solution & Example Answer:Differentiate, with examples, between an electrical insulator and an electrical conductor. - Leaving Cert Engineering - Question f - 2011
Step 1
Electrical Insulator
Answer
Electrical insulators are materials that prevent the flow of electric current. They act as barriers to electricity, hence stopping current from passing through. Examples of electrical insulators include PVC (polyvinyl chloride) used in electrical cabling and rubber, which is often used as an insulating material for wires.
Step 2
Electrical Conductor
Answer
Electrical conductors are materials that allow electric current to flow through them easily. They have free electrons that facilitate the movement of charge. Common examples of electrical conductors include metals such as aluminum and copper, which are widely used in electrical wiring and components.
