Question

Why does an electric bulb get fused?how it can be prevented?

Answer 1

Answer:

A bulb is said to be fused when the filament gets broken.we can prevent it by when we stop the condition of overloading .

Answer 2

While electricity passes through the filament of a bulb it produces heating effect and the filament starts to glow. Now if this heating reaches the temperature of the melting point of the material of that filament it will result in a open circuit situation (normally we call it that the bulb is fused).

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.
