Answer:
Explained below.
Step-by-step explanation:
In electric heaters, the wire used is nichrome wires and it can resist oxidation. Whereas, in electric bulbs, wires used are called tungsten and they undergo Oxidation begins at high temperatures between 500°C and 1200°C. Therefore, we would can't interchange because tungsten wires need a protective film/inert gas to withstand the high temperatures so that the wires don't get weak and break.
