प्रश्न
How does an electric fuse prevent the electric circuit and the appliances from a possible damage due to short circuiting or overloading.
उत्तर
The fuse used in electrical circuits is a typical example of Joule's heating in action. It safeguards appliances and circuits by halting the flow of any excessively high electric current. The device and fuse are connected in series. It is composed of a wire made of a metal or alloy with an appropriate melting point, such as lead, copper, iron, or aluminium. The temperature of the fuse wire rises if a current greater than the allowed amount flows through the circuit. The fuse wire melts as a result, breaking the circuit. Typically, the fuse wire is enclosed in a porcelain or similar material cartridge with metal ends.
