Why does a cord of an electric heater not glow while the heating element does |
|
Answer» Because the heating element of an electric heater is made of an alloy and have high resistance whereas the cord of an electric heater is made of a copper metal which has very very low resistance.The heating element of an electric heater is made of nichrome glows because it becomes red hot due to large amount of heat produce on passing current whereas the cord of an electric heater is made of copper that doesn\'t glow because produce in it by passing the same current Because chord of wire is made up of good conducter of electricity which have negligible resistance |
