Worked Solution & Example Answer:Differentiate, with examples, between an electrical insulator and an electrical conductor - Leaving Cert Engineering - Question f - 2011
Step 1
Differentiate, with examples, between an electrical insulator and an electrical conductor.
Answer
An electrical conductor is a material that allows electricity to flow through it easily. This is due to the presence of free electrons that can move under the influence of an electric field. Common examples of electrical conductors include metals such as copper and aluminum.
Conversely, an electrical insulator is a material that does not allow electricity to flow through it easily. Insulators have tightly bound electrons, which prevent the movement of electric charge. Examples of electrical insulators include rubber, glass, and plastic.
Step 2
Outline two reasons why tubular steel is a suitable material for this table.
Answer
-
Strength-to-Weight Ratio: Tubular steel possesses a good strength-to-weight ratio, making it durable yet lightweight. This enhances the structural integrity of the table while ensuring it remains functional and easy to handle.
-
Fabrication Versatility: Tubular steel can be easily fabricated into various shapes, including curved designs. This flexibility in manufacturing allows for innovative and aesthetic designs, making it ideal for designer furniture.
