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

Answer 1

Answer:

Because of the material that's used.

Explanation:

The cord of an electric heater is made using a material that does not produce light in the visible region. The main purpose of this coil is to generate heat, not light.

Note: The coil produces light, which can't be seen by us. The frequency of this radiation falls outside the visible region.

The heating element of a bulb is designed using an alloy of Tungsten, that produces light in the visible region.
