A fused bulb does not glow because the electrical circuit inside it is broken. Here’s why does a fused bulb not glow,
Understanding the filament: A standard incandescent bulb has a thin wire filament, usually made of tungsten. When electricity flows through it, the filament resists the current slightly, producing heat and light.
Role of the filament: The filament completes the electrical circuit inside the bulb. Current flows from one contact point, through the filament, and back to the socket, allowing the bulb to emit light.
What happens when a bulb fuses: Over time or due to sudden voltage spikes, the filament can melt or break. This break in the filament is what is referred to as the bulb being “fused.”
Circuit interruption: Once the filament is broken, the electrical path inside the bulb is interrupted. Electricity cannot pass through a broken filament, so the current stops flowing.
No energy conversion: Since the current cannot flow, the bulb cannot convert electrical energy into heat and light. This is why the bulb remains dark even if it is connected to a live power source.
Visual check: Often, a fused bulb filament appears visibly broken or blackened. In some cases, the bulb glass may also show discoloration due to burning of the filament.
In short, a fused bulb does not glow because the filament, which is crucial for completing the electrical circuit and producing light, has broken, preventing the flow of electricity.

At times we wonder a fused bulb does not glow why? This is a very interesting question. I will break it down in simple words so that you can understand the process behind why does a fused bulb not glow.
'To fuse' means to melt. It represents that the filament of the bulb has melted and it has broken therefore there is no ongoing circuit. Since there is no current flowing this is the reason why a fused bulb does not glow.
An electric bulb has in it a coiled tungsten filament. The current goes through the filament and it glows with white colour as it turns hot. The fused bulb signifies an electric bulb that has melted. Since the filament melts the circuit opens, and so the current stops flowing through the filament. The filament stops heating up and does not glow anymore.
Just like the heat of infusion of water which denotes the amount of heat needed to melt 1gm of ice at 0 degrees Celcius to 1 gm of water at 0 Degree Celsius, to fuse denotes to melt. Due to the tremendous flow of current, the filament of the bulb has melted.
It's better to throw the fused bulb and install a bulb since the old bulb stops working.
