What is conductors and insulators?
Answers
Answer:
Conductors are materials that permit electrons to flow freely from particle to particle. ... Conductors allow for
charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.
Conductors - Thermal conductivity is the property of material to conduct heat from it. Metals are good examples as they contain high concentration of free electrons. Substances having high thermal conductivity are conductors.
Examples - Copper, Gold, Iron, etc. metals are examples of conductors.
_______________________________
Insulators - A substances which is poor conductor of heat electricity are insulators. Insulators are poor conductors because of the lack of mobile (free) electrons.
Examples - Rock wool, Fiberglass, White pine, window glass etc.
