Question

why does the connecting rod of an elctric heater not glow while heating element does

Answer 1

An electric heater works on the principle of the heating effect of electric current.The heating element of the heater blocks the electric current and does not let it pass. So the heating element gets heated and glows due the heat. It has high resistivity , so it does not melt. The cord of the electric heater is a good conductor of electricity so it does not get heated up and also does not glow.
