easily transfer these types of energy. A conductor is something which allows electric current to flow through it freely whereas an insulator prevents any electric current flowing through it. Consider your everyday electrical wire, which conducts the electricity through the copper core and is insulated by a polymer complex. A semiconductor is a material that is neither a good conductor or a good insulator but that conducts more electricity when heat, light or voltage is added. Semiconductor...
