Question

⦠why does the cord of an electric heater not glow while heating element does?

Answer 1

pura pagal hain kya dost

Good question

Answer 2

The heater element glows because it has a relatively high resistance than that of the cord. Which means that the power dissipated across the element ( Hence the glow ) is very much higher than the power dissipated across the cord which should be extremely small in a properly designed appliance.
