When do we use insulators in everyday life?

Answer 1

Insulators are used in everyday life to prevent the flow of electricity and heat, ensuring safety and efficiency. For example, rubber and plastic coatings on electrical wires protect users from electric shocks. In construction, materials like fiberglass and foam are used to insulate buildings, keeping them warm in winter and cool in summer. Additionally, insulators are found in household appliances, such as coffee mugs with double walls to retain heat while keeping the exterior cool.
