For normal applications, an electric fuse wire must have a low melting point alloy and be thin with less length. These properties ensure that the fuse wire melts quickly when excessive current flows, breaking the circuit effectively and protecting electrical ...

The filament of an electric bulb is made of tungsten. Tungsten is chosen for its high melting point and ability to withstand intense heat without melting, making it ideal for producing light when an electric current passes through it.
The loud sound when a bulb is broken occurs because air enters rapidly into the vacuum inside the bulb. The sudden influx of air into the vacuum creates a pressure difference, causing the loud noise as the vacuum is disrupted.
Air is completely removed from an electric bulb to create a vacuum or fill it with an inert gas, which prevents the tungsten filament from reacting with oxygen. This helps to prolong the life of the bulb.
The electrical energy in the tube is almost completely converted into light energy. Fluorescent tubes are preferred over electric bulbs because they are more efficient at converting electrical energy into visible light, reducing energy wastage and providing brighter illumination.
