Want this question answered?
Materials that allow energy to flow easily through it are called conductors.
Anything that is classified as a conductor will allow the flow of electrons.
Materials that do not allow electric currents to pass are called insulators.
Because of freely moving of electrons in the material
Conductors.
Materials that allow energy to flow easily through it are called conductors.
Those are called insulators.
They are called "insulators" and include such materials as glass, rubber, plastic, nylon, dry wood, ceramic, air, etc.
a brick i think
radiation
no
bad conductors
insulator...as opposed to a conductor which does allow electrons to travel freely within it.
Isolators.
A conductor. Most metals are conductors-they enable electrons to move freely through them, carrying an electrical charge. Most non-metals (notably excluding graphite, an isotope of carbon) are insulators which means that they do not allow an electrical charge to be carried through them.
Conductors are materials that allow electrons to flow easily through it. Metals are the best examples of conductors. Insulators to the opposite; they don't like letting their electrons flow. Glass, rubber, and wood are some examples of insulators.
