GEOLOGY

Detailed explanation-1: -As rubber is the only non-metal on the list, so it is an electrical insulator.

Detailed explanation-2: -Rubber materials feature excellent electrical insulation capabilities, making them useful for preventing the dangerous effects caused by electricity transferring to other objects. Rubber slows down electrons, making it the most natural and efficient insulator in the world.

Detailed explanation-3: -Some common insulator materials are glass, plastic, rubber, air, and wood. Insulators are used to protect us from the dangerous effects of electricity flowing through conductors.

Detailed explanation-4: -Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.

Detailed explanation-5: -Rubber is known to be an insulator because rubber can limit the transfer of electricity. The rubber properties prevent the electrons to be able to freely move and the addition of the electrons being tightly bounded makes rubber a good insulator .
