The electrical cord that carries power to an electrical appliance is made up of copper conductors that are very low in resistance to the flow of electric current so very little heat is given off when the appliance is in use. In order to convert electric current into heat, the wire used to make a heating element is usually a high electrical resistance steel wire that is sized small enough so that it is not a very good conductor so the wire heats up and glows cherry red such as the heat element that can be seen inside a bread toaster.
