Answer 2

Answer:

The bulb must be fused.

Explanation:

An electric bulb or a torch bulb contains a filament of tungsten metal which heats up due to electricity and due to the heat, the tungsten filament glows - producing light.

If the bulb is not glowing in the closed circuit, then the bulb must be fused....that is; the filament must have been broken....
