A bulb gets fused when short circuit occurs or high voltage passes
Fused bulb
A fused bulb does not light up asno current passes through its filament. by j.gayathri
When a bulb fuses the circuit is broken if it is on a serial circuit. If the bulb is on a parallel circuit, only the fused bulb will go out, any other bulb would remain lit. On a serial circuit, until the bulb is replaced by a new one, the circuit is not able to be used.
A bulb is said to be fused if the filament gets broken . Fused bulb doesn't glow. The two terminals do not directly touch each other to avoid short circuit.
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
because of the heat inside the bulb
the bulb get fused
When a bulb is brown the whole bulb would be shaded brown and would be the same shade all over. When a bulb has blown or fused then firstly part of the bulb would be brown the rest of the bulb would be the original colour. Secondly the the internal element that looks like a spring will have broken and roll around inside the bulb.
Either the bulb gets blown itself or the tungsten wire melts and opens the circuit, causing the light bulb to fuse.
Because the fuse acts as a surge protector.
Because the bulb fused or toothpick is not the good conductor of eletricity.
