Question

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

please don't delete my question ​

Answer 1

$\bold\red{\underline{\underline{Answer:}}}$

The heater's heating element consists of an alloy that has very high resistance, so that when the current flows through the heating element it becomes too hot and glows red. ... But the cord's resistance where the cord is normally made of copper or aluminium is very small so it doesn't glow.
