Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which material is an insulator?
A
gold
B
copper
C
plastic
D
None of the above
Explanation: 

Detailed explanation-1: -Plastics are good electrical insulators (such as phenolic, Ultem®, PEEK ). There are dozens of polymers to choose from that offer high dielectric strength and excellent fire resistance.

Detailed explanation-2: -Plastics are excellent insulators, meaning they can efficiently trap heat-a quality that can be an advantage in something like a coffee cup sleeve.

Detailed explanation-3: -Certain types of plastics, like Mylar® & Melinex® polyester films, are excellent insulators, which means they can effectively trap heat. Plastics offer a variety of properties that allow them to be used across many different industries, as well as the insulation of electrical wires.

Detailed explanation-4: -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-5: -The insulator is a material in which the electron does not flow freely. The atom of the insulator has tightly bound electrons. Examples of insulators include plastics, paper, rubber, glass and bakelite, Mica, Porcelain.
