Is Cloth A Conductor Or Insulator
Is Cloth A Conductor Or Insulator. Air is excellent at convection, but the amount of heat that can be transferred is minimal because the low mass of the substance cannot store a great deal of heat. Air is used as an insulator in coolers and building walls.
Generally all metals (iron, gold, silver, copper, aluminum, zinc etc.) are conductive. These materials are known as electrical insulators. As discussed in the previous section, electrons surround the tiny nucleus in the form of a (comparatively) vast cloud of negative charge.
