Question

A fused bulb does not glow. Why?

Answer 1

Bulb

1. When electricity is transmitted through the terminals of an electric bulb, it creates light. If the filament of a bulb breaks, it is said to be fused. The fused bulb does not light up.
2. In the center of the bulb, there are two thick contact wires with a thin wire connecting them. The filament is the term for this tiny wire.
3. One of the heavy wires is attached to the metal case at the bulb's base, while the other is attached to the metal tip in the center. The terminals are made up of these two.
4. The filament heats up and produces light when electricity is delivered through the bulb's terminals.
5. Since the filament is broken, the circuit is incomplete, and thus, the bulb will not glow. 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.
6. The below diagram is showing a fused bulb with a broken filament.

Hence, a fused bulb does not light up as no current passes through its filament.
