The principle of a fuse is based on the thermal effect of electricity. A fuse wire melts due to the heat generated by an excessive current, thereby breaking the circuit and preventing damage. This thermal effect ensures that the fuse ...

Fuse wire is made of an alloy of tin and lead. This combination is selected because the alloy has a low melting point, allowing the fuse to melt and break the circuit quickly when excessive current flows, thus protecting electrical ...
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.
