Question

Write a few applications of conductors and insulators.

Answer 1

Applications of Conductors:-

1. Mercury is a common material in thermometers to check the temperature of the body.
2. Aluminum finds its use in making foils to store food. It is also used in the production of fry pans to store heat quickly.
3. Iron is a common material used in vehicle engine manufacturing to conduct heat.

Application of insulators:-

1. Thermal insulators, disallow heat to move from one place to another. Hence, we use them in making thermoplastic bottles. They are also used in fireproofing ceilings and walls.
2. Sound insulators help in controlling noise level, as they are good in absorbance of sound. Thus, we use them in buildings and conference halls to make them noise-free.
3. Electrical insulators hinder the flow of electrons or passage of current through them. So, we use them extensively in circuit boards and high-voltage systems. They are also used in coating electric wires and cables.
