GEOLOGY

Detailed explanation-1: -An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials-semiconductors and conductors-conduct electric current more easily.

Detailed explanation-2: -Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Detailed explanation-3: -A conductor is a material that allows electrons to flow freely through it, making it useful for carrying electric current. An insulatoris a material that resists the flow of electrons, so it does not allow electric current to pass through it.

Detailed explanation-4: -A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it. In a conductor, electrical charge carriers, usually electrons or ions, move easily from atom to atom when voltage is applied.

Detailed explanation-5: -On the other hand, in an insulator the electrons of the outer most shell are bound with a very high electrostatic forces coming from the nucleus of each atom so electrons cannot flow around all atoms making up the material as in a conductor.
