Question

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

Answer 1

Answer:

The heater's heating element is made up of an alloy that has very high resistance, so when current flows through the heating element, it becomes too hot and glows red. But the cord's resistance, which is usually of copper or aluminium, is low, so it does not glow.

Explanation:

Answer 2

Answer:

The heating element of an electric heater is a resistor. The amount of heat produced by it is a proportional to its resistance. The resistance of the element of an electric heater is very high. As current flows through the heating element,it becomes too hot and glows red. On the other hand, the resistance of the cord is low.It does not become red when current flows through it.
