Materials like rubber and plastic, which do not allow electric current to pass through them easily, are known as what?

Explanation

Insulators are materials, such as rubber, plastic, and glass, that strongly resist the flow of electric current because their electrons are tightly bound and not free to move easily through the material. This property makes insulators essential for safety in electrical applications, such as the protective plastic or rubber coating found around electrical wires, which prevents dangerous contact with the conductive metal inside. Conductors, by contrast, such as most metals, allow electric current to flow through them relatively easily. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
