Why is fuse wire made very thin?
How does resistance in the fuse wire cause it to heat up?
Resistance acts as a choke: The resistance in the fuse wire acts as a choke to the flow of current. When current passes through a resistor like the fuse wire, it encounters resistance. This resistance converts electrical energy into heat energy, causing the wire to heat up. The more resistance there is in the wire, the more heat it generates.
Why do electric fires, light bulbs, and kettles get hot when a current flows?
Electric fires, light bulbs, and kettles: These electrical devices work by using the flow of current to generate heat. When current flows through the resistance in the heating element of electric fires, light bulbs, or kettles, the wire heats up. This heat is then used to warm a room, produce light, or boil water, depending on the device's function.
How does the fuse wire protect the device from high current surge on failure?
Protection from high current surge: The fuse wire is designed to melt or burn out when the current flowing through it exceeds the rated limit. By breaking the circuit in this way, the fuse wire prevents the high current surge from reaching the device. This protects the device from damage that could occur due to excessive current flow, such as a short circuit or a power surge.
How does the fuse wire protect human life?
Protection of human life: In addition to safeguarding the device, the fuse wire also plays a critical role in protecting human life. By breaking the circuit in the event of a current overload, the fuse wire prevents electrical accidents that could pose a risk to human safety. This safety feature ensures that users are protected from potentially harmful electrical malfunctions that could result in injuries or even fatalities.
