GEOLOGY

Detailed explanation-1: -Hence, The materials which do not allow electricity to pass through them is called as Insulators. Q.

Detailed explanation-2: -A conductor conducts electricity since it offers little or no resistance to the flow of electrons, thus leading to a flow of electrical current. Typically, metals, metal alloys, electrolytes and even some nonmetals, like graphite and liquids, including water, are good electrical conductors.

Detailed explanation-3: -Insulators such as oil, glass, rubber, and ceramics have a large band gap which prevents the flow of electrons.

Detailed explanation-4: -Conductors: Materials that offer very little resistance where electrons can move easily. Examples: silver, copper, gold and aluminum.

Detailed explanation-5: -An electrical insulator is a material through which charge cannot flow easily. A metal wire is usually coated with plastic or rubber. The metal wire is an electrical conductor. The rubber and plastic are electrical insulators.
