An electric bulb may fuse due to many reasons. One reason for a bulb to fuse is a break in its filament. A break in the filament of an electric bulb means a break in the path of the current between the terminals of the electric cell. Therefore, a fused bulb does not light up as no current passes through its filament.

Answer 2

Answer:

Electric Bulb:

An electric bulb is a device which produces light when electricity is passed through its terminals.

*The bulb has two thick contact wires in the center with a thin wire attached between them. This thin wire is called filament.

*One of the thick wires is connected to the metal case at the base of the bulb and the other is connected to the metal tip at the center of the base. These two form the terminals.

*When electricity is passed through the terminals of the bulb, the filament gets heated up and produces light.

*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.
